1 INTRODUCTION

Computer Vision is a field within artificial intelligence (AI) focused on enabling machines to
interpret visual information from the world. This interpretation can involve recognizing
objects, analyzing movements, or extracting patterns to make decisions based on visual data.
By mimicking human vision capabilities, computer vision aims to bridge the gap between
raw data in images or videos and actionable insights.

Image Processing, on the other hand, deals with manipulating images to enhance their quality
or extract meaningful information. It involves techniques such as filtering, sharpening, noise
reduction, and segmentation. While image processing often serves as a preprocessing step for
computer vision tasks, it has its standalone applications, such as in medical imaging and
remote sensing.

Together, these fields form the basis of numerous advanced technologies, leveraging
computational models to analyze and interpret visual data effectively.

1. History and Evolution

Early Years (1950s-1960s)

Artificial Intelligence (AI) and Neural Networks: The concept of AI and neural networks
emerged in the 1950s, laying the foundation for computer vision.First Image Processing
Systems: In the 1950s and 1960s, the first image processing systems were developed,
primarily for military and space applications.Robots and Machine Vision: In the 1960s,
robots and machine vision systems began to emerge, with applications in manufacturing and
inspection.
Rule-Based Approaches (1970s-1980s)

Rule-Based Systems: In the 1970s and 1980s, rule-based systems were developed for
computer vision, using hand-crafted rules to analyze images.Expert Systems: Expert systems
were also developed during this period, using knowledge-based approaches to solve
computer vision problems.Image Processing Techniques: Various image processing
techniques, such as edge detection and thresholding, were developed during this period.

Statistical and Machine Learning Approaches (1990s-2000s)

• Statistical Methods: In the 1990s, statistical methods, such as Bayesian networks and
probabilistic graphical models, began to be applied to computer vision.

• Machine Learning: Machine learning algorithms, such as support vector machines


(SVMs) and k-means clustering, were also applied to computer vision problems.

• Feature Extraction: Feature extraction techniques, such as SIFT and SURF, were
developed during this period.

Deep Learning and Convolutional Neural Networks (2010s-present)

• Deep Learning: Deep learning algorithms, particularly convolutional neural networks


(CNNs), revolutionized computer vision in the 2010s.

• Convolutional Neural Networks (CNNs): CNNs, such as AlexNet and VGGNet,


achieved state-of-the-art performance in image classification and object detection
tasks.

• Object Detection and Segmentation: Object detection and segmentation algorithms,


such as YOLO and Mask R-CNN, were developed during this period.
1.2 Different Techniques of Computer Vision:-

Image Classification

The problem of image classification goes like this: Given a set of images that are all labeled
with a single category, we’re asked to predict these categories for a novel set of test images
and measure the accuracy of the predictions. There are a variety of challenges associated with
this task, including viewpoint variation, scale variation, intra-class variation, image
deformation, image occlusion, illumination conditions, and background clutter.

fig1.1

The most popular architecture used for image classification is Convolutional Neural
Networks (CNNs). A typical use case for CNNs is where you feed the network images and
the network classifies the data. CNNs tend to start with an input “scanner” which isn’t
intended to parse all the training data at once. For example, to input an image of 100 x 100
pixels, you wouldn’t want a layer with 10,000 nodes.

Object Detection

The task to define objects within images usually involves outputting bounding boxes and
labels for individual objects. This differs from the classification / localization task by
applying classification and localization to many objects instead of just a single dominant
object. You have 2 classes of object classification, which means object bounding boxes and
nonObject bounding boxes. For example, in car detection, you have to detect all cars in a
given image with their bounding boxes.
Fig 1.2

Object Tracking

Object Tracking refers to the process of following a specific object of interest, or multiple
objects, in a given scene. It traditionally has applications in video and real-world interactions
where observations are made following an initial object detection. Now, it’s crucial to
autonomous driving systems such as self-driving vehicles from companies like Uber and

Tesla. Object Tracking methods can be divided into 2 categories according to the observation

model: generative method and discriminative method The generative method uses the
generative model to describe the apparent characteristics and minimizes the reconstruction
error to search the object, such as PCA.The discriminative method can be used to distinguish
between the object and the background, its performance is more robust, and it gradually
becomes the main method in tracking. The discriminative method is also referred to as
Tracking-by-Detection, and deep learning belongs to this category. To achieve tracking-by-
detection, we detect candidate objects for all frames and use deep learning to recognize the
wanted object from the candidates. There are 2 kinds of basic network models that can be
used: stacked auto encoders (SAE) and convolutional neural network (CNN).

Semantic Segmentation

Semantic Segmentation

Fig1.4

Central to Computer Vision is the process of segmentation, which divides whole images into
pixel groupings which can then be labelled and classified.Particularly, Semantic Segmentation
tries to semantically understand the role of each pixel in the image For example, in the picture
above, apart from recognizing the person, the road, the cars, the trees, etc., we also have to
delineate the boundaries of each object. Therefore, unlike classification, we need dense pixel-
wise predictions from our models.As with other computer vision tasks, CNNs have had
enormous success on segmentation problems. One of the popular initial approaches was patch
classification through a sliding window, where each pixel was separately classified into classes
using a patch of images around it. This, however, is very inefficient computationally because
we don’t reuse the shared features between overlapping patches

Instance Segmentation

Beyond Semantic Segmentation, Instance Segmentation segments different instances of


classes, such as labelling 5 cars with 5 different colors. In classification, there’s generally an
image with a single object as the focus and the task is to say what that image is. But in order to
segment instances, we need to carry out far more complex tasks. We see complicated
sightswith multiple overlapping objects and different backgrounds, and we not only classify
these different objects but also identify their boundaries, differences, and relations to one
another.

Fig1.5
2. FUNDAMENTALS OF COMPUTER VISION

2.1 Feature Detection

Feature detection is the process of identifying and locating interest points or features within
an image. These features can be corners, edges, blobs, or other patterns that are useful for
tasks like object recognition, tracking, and matching.

2.2 Types of Feature Detectors

❖ Corner detector

Corner detection is an approach used within computer vision systems to extract


certain kinds of features and infer the contents of an image. Corner detection is
frequently used in motion detection, image registration, video tracking, image
mosaicing, panorama stitching, 3D reconstruction and object recognition. Corner
detection overlaps with the topic of interest point detection.

Example includes ,

• Haris corner detector

• FAST
• ORB

❖ Edge detector

Edge detection is an image processing technique for finding the boundaries of objects within
images. It works by detecting discontinuities in brightness. Edge detection is used for image
segmentation and data extraction in areas such as image processing, computer vision, and
machine vision.
Examples includes,
• Cany edge detector
• Sobel operator

❖ Blob detector

blob detection refers to modules that are aimed at detecting points and/or
regions in the image that differ in properties like brightness or color compared
to the surrounding. It is used to obtain regions of interest for further processing.
These regions could signal the presence of objects or parts of objects in the
image domain with application to object recognition and/or object tracking
Blob detection is usually done after color detection and noise reduction to
finally find the required object from the image.

2.3 Object Recognition Techniques

Object recognition is a computer vision technique for identifying objects in images or


videos. Object recognition is a key output of deep learning and machine learning
algorithms. When humans look at a photograph or watch a video, we can readily spot
people, objects, scenes, and visual details. The goal is to teach a computer to do what
comes naturally to humans: to gain a level of understanding of what an image contains.

Fig2.3 using object recognition to identify different categories of objects

Object recognition is a key technology behind driverless cars, enabling them to recognize
a stop sign or to distinguish a pedestrian from a lamppost. It is also useful in a variety of
applications such as disease identification in bioimaging, industrial inspection, and
robotic vision.

2.4 How Object Recognition Works?

You can use a variety of approaches for object recognition. Recently, techniques in
machine learning and deep learning have become popular approaches to object
recognition problems. Both techniques learn to identify objects in images, but they differ
in their execution.
Fig2.4 machine learning and deep learning techniques for object recognition

The following section explains the differences between machine learning and deep
learning for object recognition, and it shows how to implement both techniques.

2.5 Machine Learning vs. Deep Learning for Object Recognition

Determining the best approach for object recognition depends on your application and the
problem you’re trying to solve. In many cases, machine learning can be an effective
technique, especially if you know which features or characteristics of theimage are the
best ones to use to differentiate classes of objects.

The main consideration to keep in mind when choosing between machine learning and
deep learning is whether you have a powerful GPU and lots of labeled training images. If
the answer to either of these questions is No, a machine learning approach might be the
best choice. Deep learning techniques tend to work better with more images, and a GPU
helps to decrease the time needed to train the model.

. Fig2.5 Key factors for choosing between deep learning and machine
learning.
2.6 Image Classification

Image classification is a fundamental task in computer vision that deals with


automatically understanding the content of an image. It involves assigning a category or
label to an entire image based on its visual content.

2.7 Types of Image Classification

1.Binary Classification

Binary classification involves classifying images into one of two categories. For
example, determining whether an image contains a cat or not. This is the simplest form of
image classification.

2. Multiclass Classification

Multiclass classification involves categorizing images into more than two classes. For
instance, classifying images of different types of animals (cats, dogs, birds, etc.). Each
image is assigned to one, and only one, category.

3. Multilabel Classification

Multilabel classification allows an image to be associated with multiple labels. For


example, an image might be classified as both “sunset” and “beach.” This type of
classification is useful when images can belong to multiple categories simultaneously.

4. Hierarchical Classification

Hierarchical classification involves classifying images at multiple levels of hierarchy. For


example, an image of an animal can first be classified as a “mammal” and then further
classified as “cat” or “dog.” This method is useful when dealing with complex datasets
with multiple levels of categories.

6.FUTURE TRENDS
6.1 The Rise of Generative AI

The recent popularity of Generative AI systems has seen organizations


everywhere rush to explore the technology’s transformative capabilities.
AI tools such as Open AI’s ChatGPT and Dall-E have improved
operations and tackled problems that would once have been impossible to
solve.

Generative AI has entered the mainstream. A host of startups, including


Hugging Face, Anthropic, Stability AI, Midjourney, and AI21 Labs will
join market leader OpenAI.

The field of computer vision will be among those exploring its potential.
Over the next 12 months, we can expect to see Generative AI further
enable synthetic data creation.

Generative AI can be used to create outputs across a variety of domains.


These can include large language models like text-to-image, text-to-
video, text-to-audio, and more.

The output data from generative models can be used to train computer
vision models, such as those for object detection or facial recognition.
Not only will this minimize the risk of privacy violations, but make the
model training process significantly less expensive and time-consuming.
This is because it labels training data faster and more efficiently than
humans.

6.2 Computer Vision in Healthcare

The impact of AI in healthcare will go far beyond improving the speed


and efficiency of health assessments.

Doctors and researchers have been using computer vision algorithms to


differentiate between healthy and cancerous tissue. This speeds up the
analysis of medical imaging and scans. In turn, doctors can quickly
identify and diagnose serious diseases and ensure accurate and timely
record-keeping. This paper, for example, proposes an application of AI
and computer vision to enable medical practitioners to promptly and
effectively diagnose breast cancer.

Computer vision will also play a variety of roles in operating theatres,


such as monitoring surgical procedures. This can track the location of
instruments and ensure the correct performance of surgeries. In turn, this
minimizes the risk of surgical instruments left

inside the patient. And, increasingly, healthcare professionals will use


augmented reality to guide – and even perform – remote surgery.

Fig 6.2

6.3 Edge Computing and Lightweight Architecture

Processing visual data directly on edge devices such as smartphones,


drones, and IoT sensors, where that data is captured, reduces latency. This
enables real time visual data processing, essential for use cases across
industries.Looking ahead, it’s likely that the growing adoption of edge
computing architecture will lead to the development of small, efficient
computer vision applications. These small applications can run on low-
power devices, a boon to manufacturing and security operations.

However, these smaller, more efficient computer vision applications will


require lightweight AI models. These can be deployed on low-power
devices with limited processing power and memory.

R-CNN (Region-based Convolutional Neural Networks) is one of the


most commonly used machine learning models. However, while R-CNN
is highly accurate for object detection, it requires heavy – and expensive
– computational resources.

In contrast, lightweight AI architectures like YOLO (You Only Look


Once), require less powerful resources. These lightweight models are the
more suitable option for edge devices.

Similarly, the high accuracy and real-time performance of the SSD


(Single Shot Detector) object detection algorithm have made it a popular
choice for a wide range of applications. These applications include AI in
autonomous vehicles and surveillance systems, among others.

6.4 Enabling Autonomous Vehicles

Self-driving cars are high on the list of key use cases for computer vision
technology. Currently, the technology used to navigate and operate
autonomous vehicles relies on processing input from various sources,
ranging from cameras and GPS to RADAR and LiDAR.

But as they become more prevalent, it’s only a matter of time before the
computers in these vehicles can drive almost entirely by sight, the same
way a human driver does. To this end, we can expect the incorporation of
increasingly sophisticated computer vision technology into the design
and production line process, as self-driving vehicles edge ever closer to
becoming an everyday reality on our roads.

fig6.4
5. Advances in 3D Computer Vision

The recent development of sophisticated algorithms has opened


more opportunities for the application of 3D computer vision.
This includes using multiple cameras to capture various angles
of objects or light sensors to measure

the time for light to reflect off an object. At present,


autonomous cars utilize both of these methods in their safety
systems.

Whether spatial or time-based, advances in 3D computer vision


will provide better-quality data on depth and distance. These
advances allow for the creation of accurate 3D models for
digital twins: precise replicas of an object, building, or person
for use in simulations.The depth of

information provided by 3D computer vision will also improve


accuracy. This can be done by leveraging depth data to
distinguish between objects in a cluttered environment, as in
the diagram below. Thereby, ensuring greater precision and
reliability.

fig6.5
7 CONCLUSION

Computer vision is a captivating branch of AI that endows


machines with the remarkable ability to interpret and understand
visual data. It bridges the gap between human perception and
machine intelligence, opening up a world of possibilities across
numerous industries. From healthcare and autonomous vehicles
to manufacturing and entertainment, the applications of
computer vision are diverse and transformative. As technology
continues to evolve, we can expect computer vision to play an
increasingly pivotal role in shaping the future of AI-driven
innovations.
