In this paper, a variable filter based on the direction of improving the method of Hough transform. The direction of the first to use this method to detect variable edge filter, as well as the direction of the edge characteristics, and then based on the edge points and their direction, by improving the center of the Hough transform, radius. Finally, the object segmentation algorithm is applied to ball games and get better results.
