for video morphing:
	run above algorithm, get point to point correlation
	B=interpolate points on now stretched image (see http://tanbakuchi.com/posts/comparison-of-openv-interpolation-algorithms/)
	for interpolated points on B, interpolate correlations
	inbetween both colour and position using correlations of image A and B
