box filtering technique for calculation of cross correlation coefficients with parallel
processing using MMX/SSE technology of modern general purpose processors. We have
used this algorithm for real time optical flow estimation between frames of video sequence.

Abstract
This paper describes a new algorithm to calculate cross-correlation function. We combined box filtering technique for calculation of cross correlation coefficients with parallel processing using MMX/SSE technology of modern general purpose processors. We have used this algorithm for real time optical flow estimation between frames of video sequence. Our algorithm was tested on real world video sequences obtained from the cameras of video surveillance system.
