A tracking repositioning algorithm using keypoint labeling

This paper reports some work undertaken during the development of a generic object tracking application based on a keypoint model. In our previous work, we proposed a keypoint labeling algorithm to distinguish object from background keypoints. This article is the continuation of this work and deals with the problem of handling object deformation using the keypoint labels. In consequence, we introduce an algorithm to refine the bounding box position according to the surrounding keypoint labels. Experimental results are shown to validate this theory.
