A New Method of Motion Detection with Biological Intelligence

The detection of moving object is the hot topic of computer vision research. In this paper, we propose a new method to detect moving object in surveillance video based on the visual features of frog eyes. The method used the principle of entropy which derived from information theory. First, we filtering out the noise and some unnecessary information in the frame images sequence used smoothing filter; Second, detecting the edge point of the smoothed image obtained in the first step by Canny operator; At last, spatial-temporal sliding windows are built for each edge point, then calculating the entropy of spatial-temporal windows and comparing the value in adjacent frames, in which the difference exceeds a certain intensity is considered as a part of moving object. Experimental results show that the proposed method can detect the edge of moving object effectively and has lower computational complexity.
