Abstract
A computer-implemented method and system determines camera movement of a new frame relative to a sequence of frames of images containing at least one dynamic object and for which relative camera movement is assumed. From changes in color values of sets of pixels in different frames of the sequence for which respective locations of all pixels in each set are adjusted so as to neutralize the effect of camera movement between the respective frames in the sequence containing the pixels, corresponding color values of the pixels in the new frame are predicted and used to determine camera movement as a relative movement of the new frame and the predicted frame. An embodiment of the invention maintains an aligned space-time volume of frames for which camera movement is neutralized and adds each new frame to the aligned space-time volume after neutralizing camera movement in the new frame.
