Cast shadow removal in motion detection by exploiting multiview geometry
Ming Xu, Lei Lü, Tianyuan Jia, Jie Ren, Jeremy S. Smith · 2012
An object detection algorithm which can remove moving cast shadows is presented. It is based on the homography mapping of foreground regions from multiple cameras. Not only the homography for the ground plane but also those for multiple parallel planes are employed. Unlike the existing geometric approaches, this algorithm removes cast shadows while keeping the feet of moving objects.
