A New Method for Tracing by Using Corner Detecting and k-Nearest Neighbor

This paper deals with object tracing using corner detecting and k-Nearest Neighbor. The goal is to determine in successive frame the object which the variable templates. The method of this paper, first used Hassris operator for corner detecting in the image, then based on the theory of K-Nearest Neighbor (KNN) to reduce the corners, Finally, used the remaining corner to construction k-polygon model for tracing. The experiment results indicated that this method can trace the abnormity object, reduce computing time as well as increase scientific property of the algorithm through statistical testing.
