This paper presents a free viewpoint video (FVV) system based on ray-space interpolation method. The new algorithm matches individual pixels in corresponding scanline pairs by using a dynamic programming technique. A sparse intermediate view disparity map is projected from matched pixels 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. The proposed method is evaluated on the Middlebury data set and compared with other methods, experimental results show that the better quality of the intermediate view is obtained and the corresponding computational complexity is reduced significantly.
