Gesture recognition using OpenCV and Python

Hand Gesture Recognition

Detects finger movements of hands and shows appropriate output.

Steps:

• Segment hand region from a real-time video sequence

  • Background Subtraction
  • Motion Detection and Thresholding
  • Contour Extraction

• Count fingers

  • Get convex hull of the segmented hand region and compute the most extreme points in the convex hull
  • Get center of palm using extremes points
  • Using center of palm, construct a circle with the maximum Euclidean distance as radius
  • Perform bitwise AND operation on thresholded hand image and the circular ROI
  • Compute count of fingers using the finger slices obtained in previous step

To run the file use: python sudo.py

Memory Intensive Operation
This script creates screenshot for every frame captured and stores it in directory 'screenshots'
Hence, there is a little delay during frame capture

To-Do List:

• Segment hand region
• Detect numbers using count of fingers
• Detect characters using finger motion
• Capture words using word motion
• Automate tasks with each character / word
