Abstract :
A novel method is proposed for activity recognition on different lighting conditions. It takes the advantage of Harris and Harris Laplace operators of capturing information in spite of extreme changing lighting conditions. They locate corners along the human body with the assistance of a human operator. Corners are followed through the images to generate a set of trajectories that represent the behavior of the human body. The method shows its effectiveness recognizing behaviors by a comparison procedure based on dynamic time warping. We present examples of recognized activities under changing lighting.
