In most scenarios, a single feature or single point movement is not enough to measure the similarity of rigid body movement. This paper exploited and expanded the method, trajectory similarity measure based on multiple movement features, and proposed a new one to calculate the similarity with multiple features instead of a single feature. Our method integrates the Canny edge detector with Hough transform to measure the similarity of rigid motions. The Canny edge detector is responsible for finding object boundaries in the images. Hough transform detects the line segment and the end points of one rigid body. And then, the similarity of rigid bodies is determined according to the point trajectory.
