Abstract. 

A fast and automatic technique for the analysis of the difference picture of two consecutive frames of a sequence to isolate the moving objects from the stationary background components is presented in this paper. The difference picture is thresholded to remove noise and windows are formed from the intensity profiles along the horizontal and vertical directions which include the moving objects only. The peaks and valleys of the histogram of the difference picture are used to identify the characteristics of the object and predict its motion.
