Real-Time Facial Emotion Detection using CNN and OpenCV
🧠 Project Summary:
This project implements a real-time facial emotion detection system using a Convolutional Neural Network (CNN) and OpenCV's Haar Cascade Classifier. It captures video from a webcam, detects faces in real time, and classifies them into one of seven emotional states: Anger, Disgust, Fear, Happy, Sad, Surprise, Neutral.
The model is trained on the FER2013 dataset and optimized for deployment in real-world scenarios. Designed with simplicity, efficiency, and educational clarity in mind, the system is ideal for student demos, educational projects, and real-time human-computer interaction research.
