GestrureRecognition

Demo at: https://www.youtube.com/watch?v=W4Afc9qcj4I

Implements a simple Convex Hull based gesture recognition and Raspberry Pi GPIO toggling.

Segmentation for convex hull is basic thresholding, hence susceptible to noises.
Take care to run in a controlled environment or feel free to add a better segmentation and use it

Raspberry Pi connection details,

For 5 fingers, Pin number 38 in board will be high
For 3 fingers, Pin number 40 in board will be high
Both pin Low when fingers closed
