You do not extract the keyframes without a lot of work. See http://www.mathworks.co.uk/matlabcentral/answers/31050-extract-the-video-keyframe

Instead you write your own code to decide which frames should be keyframes according to your calculations. See http://www.mathworks.co.uk/matlabcentral/answers/24231-how-to-extract-the-keyframes-from-video
