Dynamic programming based ray-space interpolation for free-viewpoint video system

摘要

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 program-ming technique.A sparse intermediate view disparity map is projected from matched pixels firstly,andthe 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 thedense ray-space converted from these view images.The proposed method is evaluated on the Middleburydata set arid compared with other methods,experimental results show that the better quality of the inter-mediate view is obtained and the corresponding computational complexity is reduced significantly.
