1. this function is for image (width=176, hight=144) only. but you can modify the related value to fit yours. 2. it is used to evaluate the motion vector between the Nth image and N-1th image. 3. it use Three Steps search algorithm. 4.

face detection program by matlap it detect face from given image it used ratio algorithm that golden ratio=1.6 between width and hight-face detection program by matlap it detect face from given image it used ratio algorithm that golden ratio=1.6 bet
