Upper limb rehabilitation robot is used to assist in completing rehabilitation training for patients with upper limb disorder. It is inevitable that the control system is probably disrupted by the patients in the process of rehabilitation training so that the movement of the rehabilitation robot is not smooth.

This paper presents a method of point feature tracking and online identification using SIFT(Scale Invariant Feature Transform). The proposed approach uses the probabilistic voting method with appearance model to estimate the object's optimal center and apply hierarchical vocabulary tree to recognize the object. Since SIFT feature is invariant to changes caused by rotation, scaling and illumination,...
