Accurate moving object detection is one of the most important topic for surveillance systems. Background subtraction works well for videos acquired by stationary mounted camera. However, it does not work for mounted moving cameras since the background objects also move in two consecutive frames. In this paper, we propose an optical flow based moving object(More)
Ray traversal is the most time consuming part in volume ray casting. In this paper, an acceleration technique for direct volume rendering is introduced, which uses a GPU friendly data structure to reduce traversal time. Empty regions and homogeneous regions in the volume is encoded using extended anisotropic chessboard distance (EACD) transformation. By(More)
