Improved TLD gesture tracking algorithm based on SURF and Camshift

Aiming at the situation that the traditional Camshift algorithm fails to track gestures under complicated backgrounds or short-term occlusions, an improved Camshift algorithm combined with SURF algorithm is proposed to track gestures in real time. In this method, the SURF algorithm is used to initially locate the gesture target. An improved TLD gesture tracking algorithm based on SURF and Camshift is proposed to solve the problem of large calculation amount of TLD algorithm and poor real-time tracking. The experimental results verify that the algorithm has higher accuracy and real-time performance than the traditional Camshift algorithm and the traditional TLD algorithm.
