METHOD TO IDENTIFY CONTOURS OF MOVING OBJECTS Russian patent published in 2012 - IPC G06K9/50 

FIELD: information technologies.

SUBSTANCE: method is proposed to identify contours of moving objects, including detection of moving pixels according to a principle of inter-frame subtraction, detection of direction of movement of detected pixels with account of direction of movement of adjacent pixels, generation of moving objects by combination of adjacent pixels with one direction and availability of pixels in an eight-connected vicinity, spatial differentiation of detected objects by a Sobel operator, skeletonisation of contour lines on a gradient image by the method of suppression of points of non-maximum brightness, threshold processing of a skeleton gradient image on the basis of maximum and minimum of enthropy.

EFFECT: higher accuracy in detection of areas of moving objects and higher speed for identification of image contours.
