Autocorrelation on a sequence of images

I have to perform autocorrelation on video data (a set of images). Since this is a 3D vector of informaiton, does MATLAB have any functions fit for this? I know I can use xcorr on 2D vectors, but if I have a vector of images, rather than a vector of single numbers, how can I go about performing autocorrelation? Should I decompose the video into several pixel-wise 2D vectors, or is there a simpler approach?

I think you may need to decompose the video to image sequence and the apply xcorr2 to those images.

Refer to this link for decomposing to image sequence :
