Overview:
Python is a high-level, interpreted, interactive and object-oriented scripting
language. Python is designed to be highly readable. It uses English keywords
frequently where as other languages use punctuation, and has fewer syntactical
constructions than other languages.

Python is interpreted: Python is processed at runtime by the interpreter. You

do not need to compile your program before executing it. This is similar to
Perl and PHP.

Python is Interactive: You can actually sit at a Python prompt and

interactwith the interpreter directly to write your programs.

Python is Object-Oriented: Python supports Object-Oriented style

ortechnique of programming that encapsulates code within objects.

Python is a Beginner's Language: Python is a great language for the

beginner-level programmers and supports the development of a wide range
ofapplications from simple text processing to WWW browsers to games.

History of Python:
Python was developed by Guido van Rossum in the late eighties and early
nineties at the National Research Institute for Mathematics and Computer
Science in the Netherlands. Python is derived from many other languages,
including ABC, Modula-3, C, C++, Algol-68, Small Talk, UNIX shell, and
other scripting languages. Python is copyrighted. Like Perl, Python source
code is now available under the GNU General Public License (GPL). Python
is now maintained by a core development team at the institute, although Guido
van Rossum still holds a vital role in directing its progress.

Features of Python:
Easy-to-learn: Python has few Keywords, simple structure and clearly
defined syntax. This allows a student to pick up the language quickly.
Easy-to-Read: Python code is more clearly defined and visible to the
eyes. Easy -to-Maintain: Python's source code is fairly easy-to-maintain.
A broad standard library: Python's bulk of the library is very portable and
cross platform compatible on UNIX, Windows, and Macintosh.
Interactive Mode: Python has support for an interactive mode which allows
interactive testing and debugging of snippets of code.
Portable: Python can run on the wide variety of hardware platforms and has
the same interface on all platforms.
Extendable: You can add low level modules to the python interpreter. These
modules enables programmers to add to or customize their tools to be more
efficient.
Databases: Python provides interfaces to all major commercial databases.
GUI Programming: Python supports GUI applications that can be created and
ported to many system calls, libraries, and windows systems, such as Windows
MFC, Macintosh, and the X Window system of Unix.
Scalable: Python provides a better structure and support for large programs
than shell scripting.

Apart from the above-mentioned features, Python has a big list of good
features, few are listed below:
 It support functional and structured programming methods as well as
OOP.
 It can be used as a scripting language or can be compiled to byte code
for building large applications.
 It provides very high level dynamic data types and supports dynamic
type checking.
 It supports automatic garbage collections.
 It can be easily integrated with C, C++, COM, Active X, CORBA and
JAVA.
 Environment Setup:
To set up the environment for the Emotion Recognition project, the following tools and
libraries are required:

 Python 3
 OpenCV
 NumPy
 DeepFace

To install these packages, use the following commands:

Basic Syntax of Python Program:

Type the following text at the Python prompt and press the Enter –

>>> print "Hello, Python!"

If you are running new version of Python, then you would need to use print
statement with parenthesis as in print ("Hello, Python!");.
However in Python version 2.4.3, this produces the following result –

Hello, Python!

Python Identifiers:
A Python identifier is a name used to identify a variable, function, class, module
or other object. An identifier starts with a letter A to Z or a to z or an underscore
(_) followed by zero or more letters, underscores and digits (0 to 9).Python does
not allow punctuation characters such as @, $, and % within identifiers. Python
is a case sensitive proming language.

Python Keywords:
The following list shows the Python keywords. These are reserved words and
you cannot use them as constant or variable or any other identifier names. All
the Python keywords contain lowercase letters only.
For example:
And, exec, not Assert, finally, orBreak, for, pass Class, from, print ,continue,
global, raisedef, if, return, del, import, tryelif, in, while else, is, with ,except,
lambda, yield.
Lines & Indentation:
Python provides no braces to indicate blocks of code for class and function
definitions or flow control. Blocks of code are denoted by line indentation,
which is rigidly enforced.

The number of spaces in the indentation is variable, but all statements within
the block must be indented the same amount. For example –
if True: print "True"
else:
print "False"

Command Line Arguments:

Many programs can be run to provide you with some basic information
about how they should be run. Python enables you to do this with -h −

$ python-h
usage: python [option]...[-c cmd|-m mod | file |-][arg]...

Options and arguments (and corresponding environment variables):

-c cmd: program passed in as string(terminates option list)

-d : debug output from parser (also PYTHONDEBUG=x)

-E : ignore environment variables (such as PYTHONPATH)

-h : print this help message and exit [ etc.]

Variable Types:
Variables are nothing but reserved memory locations to store values. This
means that when you create a variable you reserve some space in memory.

Assigning Values to Variables:

Python variables do not need explicit declaration to reserve memory space. The
declaration happens automatically when you assign a value to a variable. The
equal sign (=) is used to assign values to variables.
counter=10 # An integer assignment
weight=10.60 # A floating point
name="Ardent" # A string

Multiple Assignment:

Python allows you to assign a single value to several variables simultaneously.

For example −
a=b=c=1
a,b,c = 1,2,"hello"

Standard Data Types:

The data stored in memory can be of many types. For example, a person's age is
stored as a numeric value and his or her address is stored as alphanumeric
characters. Python has five standard data types −
String
List
Tuple
Dictionary
Number

Data Type Conversion:

Sometimes, you may need to perform conversions between the built-in types.
To convert between types, you simply use the type name as a function.

There are several built-in functions to perform conversion from one data type to
another.
Functions:

Defining a Function:

 def functionname( parameters ):

"function_docstring"
function_suite
return [expression]

Pass by reference vs Pass by value:

All parameters (arguments) in the Python language are passed by reference. It

means if you change what a parameter refers to within a function, the change
also reflects back in the calling function. For example –

# Function definition is here

def changeme(mylist):
"This changes a passed list into this function"
mylist.append([1,2,3,4]);
print"Values inside the function: ",mylist
return

# Now you can call changeme function

mylist=[10,20,30];
changeme(mylist);
print"Values outside the function: ",mylist

Here, we are maintaining reference of the passed object and appending values in
the same object. So, this would produce the following result −

Values inside the function: [10, 20, 30, [1, 2, 3, 4]]

Values outside the function: [10, 20, 30, [1, 2, 3, 4]]

Global vs. Local variables

Variables that are defined inside a function body have a local scope, and those
defined outside have a global scope . For Example-

total=0; # This is global variable.

# Function definition is here

def sum( arg1, arg2 ):

# Add both the parameters and return them."

total= arg1 + arg2; # Here total is local variable.

print"Inside the function local total : ", total
return total;

# Now you can call sum functionsum(10,20);

print"Outside the function global total : ", total

When the above code is executed, it produces the following result −

Inside the function local total : 30

Outside the function global total : 0

Modules:

A module allows you to logically organize your Python code. Grouping related
code into a module makes the code easier to understand and use. A module is a
Python object with arbitrarily named attributes that you can bind and reference .

The Python code for a module named aname normally resides in a file named aname.py.
Here's an example of a simple module, support.py

def print_func( par ):

print"Hello : ",
par return

The import Statement

You can use any Python source file as a module by executing an import
statement in some other Python source file. The import has the following
syntax –

import module1[, module2[,… moduleN]

Packages:

A package is a hierarchical file directory structure that defines a single Python

application environment that consists of modules and sub packages and sub-
subpackages, and so on.

Consider a file Pots.py available in Phone directory. This file has following line
of source code −
def Pots():
print "I'm Pots Phone"

Similar way, we have another two files having different functions with the same
name as above –

Phone/Isdn.py file having function Isdn()

Phone/G3.py file having function G3()

Now, create one more file init .py in Phone directory −

Phone/ init .py

To make all of your functions available when you've imported Phone, you need
to put explicit import statements in init .py as follows −
from Pots import Pots
from Isdn import Isdn
from G3 import

Numpy:

NumPy is a library for the Python programming language, adding support for
large, multi-dimensional arrays and matrices, along with a large collection of
high-level mathematical functions to operate on these arrays. The ancestor of
NumPy, Numeric, was originally created by Jim Hugunin.
NumPy targets the CPython reference implementation of Python, which is a
non-optimizing bytecode interpreter. Mathematical algorithms written for this
version of Python often run much slower than compiled equivalents.
Using NumPy in Python gives functionality comparable to MATLAB since they
are both interpreted, and they both allow the user to write fast programs as long
as most operations work on arrays or matrices instead of scalars.
Scipy:
Scientific computing tools for Python
SciPy refers to several related but distinct entities:

 The SciPy ecosystem, a collection of open source software for scientific

computing in Python.
 The community of people who use and develop this stack.
 Several conferences dedicated to scientific computing in Python - SciPy,
EuroSciPy, and SciPy.in.
 The SciPy library, one component of the SciPy stack, providing many
numerical routines.

The SciPy ecosystem

Scientific computing in Python builds upon a small core of packages:

 Python, a general purpose programming language. It is interpreted and

dynamically typed and is very well suited for interactive work and quick
prototyping, while being powerful enough to write large applications in.
 NumPy, the fundamental package for numerical computation. It defines the
numerical array and matrix types and basic operations on them.
 The SciPy library, a collection of numerical algorithms and domain-specific
toolboxes, including signal processing, optimization, statistics, and much
more.
 Matplotlib, a mature and popular plotting package that provides publication-
quality 2-D plotting, as well as rudimentary 3-D plotting.

On this base, the SciPy ecosystem includes general and specialised tools for
data management and computation, productive experimentation, and high-
performance computing. Below, we overview some key packages, though there
are many more relevant packages.

Data and computation:

 pandas, providing high-performance, easy-to-use data structures.

 SymPy, for symbolic mathematics and computer algebra.
 NetworkX, is a collection of tools for analyzing complex networks.
 scikit-image is a collection of algorithms for image processing.
 scikit-learn is a collection of algorithms and tools for machine learning.
 h5py and PyTables can both access data stored in the HDF5 format.
Productivity and high-performance computing:

 IPython, a rich interactive interface, letting you quickly process data and test
ideas.
 The Jupyter notebook provides IPython functionality and more in your web
browser, allowing you to document your computation in an easily
reproducible form.
 Cython extends Python syntax so that you can conveniently build C
extensions, either to speed up critical code or to integrate with C/C++
libraries.
 Dask, Joblib or IPyParallel for distributed processing with a focus on
numeric data.

Quality assurance:

 nose, a framework for testing Python code, being phased out in preference
for pytest.
 numpydoc, a standard and library for documenting Scientific Python
libraries.

Pandas:
In computer programming, pandas is a software library written for the Python
programming language for data manipulation and analysis. In particular, it offers
data structures and operations for manipulating numerical tables and timeseries.
It is free software released under the three-clause BSD license. "Panel data", an
econometrics term for multidimensional, structured data sets.

Library features:

 Data Frame object for data manipulation with integrated indexing.

 Tools for reading and writing data between in-memory data structures
and different file formats.
 Data alignment and integrated handling of missing data.
 Reshaping and pivoting of data sets.
 Label-based slicing, fancy indexing, and sub setting of large data sets.
 Data structure column insertion and deletion.
 Group by engine allowing split-apply-combine operations on data sets.
 Data set merging and joining.
  Hierarchical axis indexing to work with high-dimensional data in a lower-
dimensional data structure.
 Time series-functionality: Date range generation.

Python Speech Features:

This library provides common speech features for ASR including MFCCs and
filterbank energies. If you are not sure what MFCCs are, and would like to know
more have a look at this MFCC
tutorial: http://www.practicalcryptography.com/miscellaneous/machine-
learning/guide-mel-frequency-cepstral-coefficients-mfccs/.

You will need numpy and scipy to run these files. The code for this project is
available at https://github.com/jameslyons/python_speech_features .

Supported features:

 python_speech_features.mfcc() - Mel Frequency Cepstral Coefficients

 python_speech_features.fbank() - Filterbank Energies
 python_speech_features.logfbank() - Log Filterbank Energies
 python_speech_features.ssc() - Spectral Subband Centroids

To use MFCC features:

from python_speech_features import mfccfrom python_speech_features import

logfbankimport scipy.io.wavfile as wav

(rate,sig) = wav.read("file.wav")

mfcc_feat = mfcc(sig,rate)fbank_feat = logfbank(sig,rate)

print(fbank_feat[1:3,:])
OS: Miscellaneous operating system interfaces

This module provides a portable way of using operating system dependent

functionality. If you just want to read or write a file see open(), if you want to
manipulate paths, see the os.path module, and if you want to read all the lines in
all the files on the command line see the fileinput module. For creating temporary
files and directories see the tempfile module, and for high-level file and directory
handling see the shutil module.

Notes on the availability of these functions:

The design of all built-in operating system dependent modules of Python issuch
that as long as the same functionality is available, it uses the same interface; for
example, the function os.stat(path) returns stat information about path in the same
format (which happens to have originated with the POSIX interface).

Extensions peculiar to a particular operating system are also available through the
os module, but using them is of course a threat to portability.

All functions accepting path or file names accept both bytes and string objects,
and result in an object of the same type, if a path or file name is returned.

On VxWorks, os.fork, os.execv and os.spawn*p* are not supported.

Pickle: Python object serialization

The pickle module implements binary protocols for serializing and de-
serializing a Python object structure. “Pickling” is the process whereby a
Python object hierarchy is converted into a byte stream, and “unpickling” is the
inverse operation, whereby a byte stream (from a binary file or bytes-like object)
is converted back into an object hierarchy. Pickling (and unpickling) is
alternatively known as “serialization”, “marshalling,” 1 or “flattening”; however,
to avoid confusion, the terms used here are “pickling” and “unpickling”.
Operator: Standard operators as functions

The operator module exports a set of efficient functions corresponding to the

intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the
expression x+y. Many function names are those used for special methods, without
the double underscores. For backward compatibility, many of these have a variant
with the double underscores kept. The variants without the double underscores are
preferred for clarity.

The functions fall into categories that perform object comparisons, logical
operations, mathematical operations and sequence operations.

Tempfile: Generate temporary files and directories

This module creates temporary files and directories. It works on all supported
platforms. TemporaryFile, NamedTemporaryFile, TemporaryDirectory, and
SpooledTemporaryFile are high-level interfaces which provide automatic cleanup
and can be used as context managers. mkstemp() and mkdtemp() are lower-level
functions which require manual cleanup.

All the user-callable functions and constructors take additional arguments which
allow direct control over the location and name of temporary files and directories.
Files names used by this module include a string of random characters which
allows those files to be securely created in shared temporary directories. To
maintain backward compatibility, the argument order is somewhat odd; it is
recommended to use keyword arguments for clarity.
Introduction to Machine Learnning:

Machine learning is a field of computer science that gives computers the ability
to learn without being explicitly programmed.
Evolved from the study of pattern recognition and computational learningtheory
in artificial intelligence, machine learning explores the study and construction of
algorithms that can learn from and make predictions on data.

Machine learning is a field of computer science that gives computers the ability
to learn without being explicitly programmed.

Arthur Samuel, an American pioneer in the field of computer gaming and

artificial intelligence, coined the term "Machine Learning" in 1959 while at IBM.
Evolved from the study of pattern recognition and computational learningtheory
in artificial intelligence, machine learning explores the study and construction of
algorithms that can learn from and make predictions on data

Machine learning tasks are typically classified into two broad categories,
depending on whether there is a learning "signal" or "feedback" available to a
learning system:-

Supervised Learning:
Supervised learning is the machine learning task of inferring a function from
labeled training data.[1] The training data consist of a set of training examples. In
supervised learning, each example is a pair consisting of an input object (typically
a vector) and a desired output value.

A supervised learning algorithm analyses the training data and produces an

inferred function, which can be used for mapping new examples. An optimal
scenario will allow for the algorithm to correctly determine the class labels
for unseen instances. This requires the learning algorithm to generalize
from the training data to unseen situations in a "reasonable" way.

Unsupervised Learning:
Unsupervised learning is the machine learning task of inferring a function
to describe hidden structure from "unlabelled" data (a classification or
categorization is not included in the observations). Since the examples
given tothe learner are unlabelled, there is no evaluation of the accuracy
of the structurethat is output by the relevant algorithm—which is one way
of distinguishing unsupervised learning from supervised learning and
reinforcement learning.
A central case of unsupervised learning is the problem of density estimation
in statistics, though unsupervised learning encompasses many other
problems (andsolutions) involving summarizing and explaining key features
of the data.

Linear Regression Algorithm:

Linear regression is a simple and widely used algorithm in machine learning
and statistics for predicting continuous numerical values based on input
features. It fits a linear equation to the data, where the relationship between
the dependent variable (target) and one or more independent variables
(features) is modeled as a straight line. The main goal of linear regression is
to find the best-fitting line that minimizes the difference between the
predicted values and the actual values of the target variable.

The equation of a linear regression model can be represented as:

y = b0 + b1 * x1 + b2 * x2 + ... + bn * xn

where:

y is the predicted value (the dependent variable).

b0 is the intercept term, representing the value of y when all input features
(x1, x2, ..., xn) are zero.
b1, b2, ..., bn are the coefficients (also known as slopes) of the respective
input features (x1, x2, ..., xn).
The goal of training a linear regression model is to find the best values for
the coefficients (b0, b1, b2, ..., bn) that minimize the error between the
predicted values and the actual target values in the training data. The most
common method used to find these coefficients is called "Ordinary Least
Squares" (OLS), where the sum of the squared differences between the
predicted and actual values is minimized.

Once the coefficients are determined, the model can be used to make
predictions on new data by simply plugging the feature values into the linear
equation.

Linear regression is suitable for problems where the relationship between

the target variable and the features is approximately linear. However, it may
not perform well when the relationship is highly non-linear or if there are
complex interactions between the features.

Algorithm:
 Data Collection
 Data Formatting
 Model Selection
 Training
 Testing

Data Collection: We have collected data sets of movies from online

website. We have downloaded the .csv files in which information was
present.
Data Formatting: The collected data is formatted into suitable data sets.
Model Selection: We have selected different models to minimize the error
of thepredicted value. The different models used are Linear Regression Linear
Model.
Training: The data sets was divided such that x_train is used to train the
modelwith correspondingx_test values and some y_train kept reserved for
testing.
Testing: The model was tested with y_train and stored in y_predict .
Bothy_train and y_predict was compared.
 EMOTION RECOGNITION

Emotion Recognition is a crucial and interesting task in the field of computer vision,
impacting various sectors such as healthcare, security, and human-computer interaction. In
this project, we aimed to create an Emotion Recognition model using a combination of
OpenCV for face detection and DeepFace for emotion analysis. This project serves as an
introductory exploration of applying machine learning to emotion recognition.

Emotion Recognition is a complex task that involves various facial features and
expressions. While using pre-trained models like those in DeepFace can provide effective
results, the challenge lies in accurately interpreting subtle differences in expressions and
emotions.

Here are the steps to create a simple Emotion Recognition model:

1. Environment Setup: Install the necessary libraries and tools, including OpenCV,
NumPy, and DeepFace.
2. Face Detection: Use OpenCV to capture video from the webcam and detect faces in
real-time using a pre-trained Haar Cascade classifier.
3. Emotion Prediction: Use the DeepFace library to analyze the detected faces and
predict the emotions.
4. Real-Time Processing: Integrate face detection and emotion prediction to process
video frames in real-time and display the results.
5. Model Evaluation: Evaluate the performance of the Emotion Recognition system by
testing it with various facial expressions and ensuring accurate emotion classification.
6. Result Visualization: Visualize the detected faces and predicted emotions by
drawing bounding boxes and emotion labels on the video frames.
7. Future Enhancements: Explore additional features and improvements, such as
handling multiple faces, improving prediction accuracy, and integrating with other
systems.
 Actual codes for Emotion Recognition:

OUTPUT:
 Conclusion:
This project demonstrates the capability of combining OpenCV and DeepFace to perform
real-time Emotion Recognition. The integration of these technologies provides an effective
solution for emotion recognition tasks.

Future Scope:

The current Emotion Recognition project lays a solid foundation for real-time emotion
recognition using OpenCV and DeepFace. However, there are several areas for potential
improvement and expansion:

1. Enhanced Emotion Recognition Accuracy

 Improved Training Data: Utilize a larger and more diverse dataset for training to
improve the accuracy and robustness of Emotion Recognition across different
ethnicities, age groups, and lighting conditions.
 Advanced Models: Incorporate more sophisticated deep learning models, such as
Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs), to
capture complex patterns and temporal dependencies in facial expressions.

2. Multimodal Emotion Recognition

 Audio-Visual Integration: Combine facial expressions with audio analysis (e.g.,

tone of voice) to enhance emotion recognition accuracy. Multimodal systems can
provide a more comprehensive understanding of emotional states.
 Physiological Signals: Integrate physiological data, such as heart rate and skin
conductance, to improve Emotion Recognition, especially in high-stress
environments.

3. Real-Time Performance Optimization

 Model Optimization: Optimize the Emotion Recognition model for real-time

performance by reducing its computational complexity and memory footprint.
 Hardware Acceleration: Leverage hardware acceleration techniques, such as GPU
processing and Tensor Processing Units (TPUs), to speed up Emotion Recognition
and analysis.
 4. Emotion Recognition in Group Settings

 Multiple Faces: Extend the system to handle multiple faces in a single frame,
ensuring accurate Emotion Recognition for each individual in group settings.
 Interaction Analysis: Analyze interactions between individuals in a group to
understand collective emotional dynamics and social behaviors.

5. Context-Aware Emotion Recognition

 Contextual Information: Incorporate contextual information, such as the

surrounding environment and situational context, to enhance the accuracy and
relevance of Emotion Recognition.
 Behavioral Analysis: Combine Emotion Recognition with behavioral analysis to
provide insights into user intent and engagement levels.

6. Application Integration

 Smart Mirrors: Implement Emotion Recognition in smart mirrors to provide

personalized feedback and recommendations based on the user's emotional state.
 Customer Service Bots: Integrate Emotion Recognition into customer service bots to
enable empathetic and responsive interactions with users.
 Security Systems: Utilize Emotion Recognition in security systems to identify
suspicious behaviors and potential threats in real-time.

7. Privacy and Ethical Considerations

 Data Privacy: Ensure the system adheres to data privacy regulations and ethical
guidelines, protecting user data and maintaining transparency in how the data is used.
 Bias Mitigation: Address and mitigate biases in Emotion Recognition models to
ensure fair and equitable performance across different demographic groups.

8. Cross-Platform Deployment

 Mobile Applications: Develop mobile applications for Emotion Recognition,

enabling users to access the technology on-the-go.
 Cloud-Based Services: Create cloud-based Emotion Recognition services to provide
scalable and accessible solutions for various industries and applications.
