Introduction
Hey everyone! I just built a real-time smile detector using Python and OpenCV ๐. This project detects faces and identifies smiles in a live video feed from a webcam. It's simple, lightweight, and a great way to experiment with computer vision!
How It Works
The smile detector uses Haar cascade classifiers, a popular feature-based object detection method in OpenCV. The script:
โ
Captures video from a webcam ๐ท
โ
Detects faces using the Haar cascade face detector ๐ค
โ
Detects smiles within the detected face region ๐
โ
Draws rectangles around smiles in real time
Technologies Used
๐น Python 3.x ๐
๐น OpenCV (cv2) ๐
๐น Haar Cascade Classifier ๐
Installation & Usage
Want to try it out? Follow these simple steps:
1๏ธโฃ Clone the repo:
git clone https://github.com/Sripadh-Sujith/Realtime_smile_detector.git
cd Realtime_smile_detector
Applications
๐ Fun AI applications
๐ Emotion analysis
๐ค Human-computer interaction
๐ญ Sentiment detection in live streams
Whatโs Next?
I plan to improve this project by:
Implementing deep learning-based smile detection using CNNs ๐ง
Adding emotion classification for better accuracy ๐ญ
Optimizing performance for real-time applications
