摘要

To obtain and update the kernel-bandwidth,we present an adaptive bandwidth obtainment algorithm based on object contour extraction from optical-flow field.The combination of modified mountain cluster approach and fast scanning window contour extractor guarantees the speed of this algorithm.A novel ellipse detection method based on a modified RANSAC is adopted to reduce the noise.Experimental results demonstrate that the algorithm select the proper size of tracking kernelbandwidth with minor extra computational overhead and keep up with the object robustly when the scale changed rapidly.
