Implementation Face detection implementation Original image Grayscale image

Move from RGB colour space to HSV colour space For grayscale image H = 0, S = 0, 0 < = v <= 100 H = 0, S = 0, V = 100 represents a white pixel.

Eliminate white background by setting a threshold of V < 90

struct Pixel { int red; int green; int blue; int mark; } If a pixel V value is less than 90 we set mark equal 1
