Combined method of moving objects detection and identification is suggested. It based on comparative analysis of existing methods of moving objects detection that use contour analysis. Suggested method can be used in ground, sea and air control systems. The system of moving objects automatic detection with use of contour analysis was developed. It allows detection of several moving objects simultaneously because of combination of following criteria: erosion, dilation, Canny edge detector, interframe disparity, Lucas-Kanade optical flow. Software and algorithm were developed to achieve this aim. This system is used together with object tracking system as source of its input data. It allows detection probability increasing and false responses risk reducing.
