Real-time Gesture Recognition in Videos

Problem Statement

To detect hand and head motion gestures through webcam and to display corresponding left/right arrows to show direction of motion.

Approach

I used OpenCV libraries for this project.

1. A Skin color range filter created in HSV colorspace was used to identify skin colored regions.

2. Once the regions were identified, their contours are drawn using contour segmentation.

3. The centroid is calculated for the contours using moments.

4. Based on the direction of movement of the centroid, the corresponding direction of motion is displayed on the screen.
