摘要：NOVELTY - The method involves obtaining an image of a video frame for extracting a seed point of a target. Local sensitive histogram tracing process is performed by using a video target. Target position information is extracted. Random walk algorithm is obtained based on RGB color space. Video outline information is obtained by using a present video frame. A pixel value of the image is determined based on present seed point. Displacement of the present video frame and a next video frame are calculated. Video is moved from the present video frame to a next video frame. USE - Locality sensitive histogram based dynamic video target trace extracting method. ADVANTAGE - The method enables realizing dynamic target tracking process and video extracting process based on illumination changing condition. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a locality sensitive histogram based dynamic video target trace extracting method. '(Drawing includes non-English language text)'
