Sign language detection with Python and Scikit Learn | Landmark detection | Computer vision tutorial

In this tutorial, the speaker demonstrates how to build a sign language detection system using Python, OpenCV, MediaPipe, and Scikit-learn. The project focuses on recognizing specific American Sign Language (ASL) letters (A, B, and L) through hand gestures captured via webcam.

Key Technological Concepts and Product Features:

• Libraries Used:
  • OpenCV: For image processing and capturing video from the webcam.
  • MediaPipe: For detecting hand landmarks, which are crucial for classifying hand gestures.
  • Scikit-learn: For implementing machine learning models, specifically a Random Forest classifier.
• Project Workflow:
  • Data Preparation: Collect samples of hand gestures for each sign (A, B, L) by moving the hand towards and away from the camera. This creates a diverse dataset.
  • Landmark Detection: Use MediaPipe to extract hand landmarks from the captured images, reducing the dimensionality of the input data while preserving essential information.
  • Classifier Training: Train a Random Forest classifier using the extracted landmark data to recognize the signs.
  • Model Evaluation: Test the classifier's accuracy, which achieved 100% performance in the demonstration.
  • Real-time Testing: Implement a real-time application that uses the trained model to classify signs detected by the webcam.
• Data Management: The tutorial emphasizes saving the dataset and the trained model using Python's pickle library for future use.
• Visualization: The speaker includes visual feedback by drawing bounding boxes and displaying the predicted sign on the video feed.
