The python code detects different landmarks on the face and predicts the emotions such as smile based on it. It automatically takes a photo of that person when he smiles. Also when the two eyebrows are lifted up, the system plays a music automatically and the music stops when you blink your right eye.

Face detection and replace stikers with face, eye and lip - Face align with eyes

Smile Detector - using OpenCV to detect smiling faces in a video or live webcam

A face, eyes, and smile detector using Haar-like features with OpenCV.

A simple face and smile detector for Raspberry Pi and Sense HAT.

This is an OpenCV application for face, eyes, smile detection. It uses haarcascade provided by OpenCV

An easy-to-use, lightweight yet powerful CNN-based AI that can accurately recognize smiley and sad faces from 100×100 pixel drawings, capable of handling variations in position, size, and small noise.

In this project 4 distinct tasks (gender detection (A1), smile detection (A2), face-shape recognition (B1), eye-color recognition (B2)) are adressed following 4 different approaches and exploiting the potentialities of CNNs and HOG descriptors along with SVMs.

This is a simple python script that takes a selfie when it detects a smile.

How to make a Smile Detector using opencv

A Realtime Smile Detection Application built using OpenCV in Python detects a smile on the face.

A very simple implementaion of python and opencv to detect faces and smiles in a frame or web cam.

Smile Detection using open cv and haar cascades

:)

Detects faces, eyes and smiles while capturing and streaming live video

Some fun projects like snake game, Tic Tac Toe, stop watch etc.

Face and Smile Detection using OpenCV library and few pre coded haar cascade classifiers

It's a basic program that uses the primary camera on the laptop to detect a smile on the face.
