Abstract
A method segments an image acquired by a sensor of a scene by first obtaining motion vectors corresponding to the image and generating a motion vanishing point image, wherein each pixel in the motion vanishing point image represents a number of intersections of pairs of motion vectors at the pixel. In the motion vanishing point image, a representation point for each motion vector is generated and distances between the motion vectors are determined based on the representation points. Then, a motion graph is constructed wherein each node represents a motion vector, and each edge represents a weight based on the distance between the nodes. Graph spectral clustering is performed on the motion graph to produce segments of the image.
