A sparse intermediate view disparity map is projected from matched dynamic programpixels firstly, and the holes （occluded pixels） are filled in by propagating the disparity of neighboring background pixels. After interpolating dense view images, an arbitrary virtual view image can be easily rendered from the dense ray-space converted from these view images.
