Human Gait Recognition based on Earth Movers Distance and Zernike Moments

In this paper, the Gait recognition includes the following stages: In stage of moving target detection, this paper uses the background subtraction to extract gait silhouette. In stage of feature extraction, using Key frame technology and Zernike Moments to extract silhouette feature. According to obtain feature data, we can use Earth Movers Distance (EMD) to recognize gait sequence.
