AbstractIn this paper, a backward mapping algorithm for novel view rendering is proposed and implemented based on the sprites with depth. By the algorithm, a novel view image could be generated from multiple reference images, and discontinuous space surfaces are allowed in the reference frames. The usual composite algorithms take much computation in warping all the reference images to the output image. In our three-step transformation process, only one primary reference frame is employed for warping the depth value during the forward mapping step. Under the observation that, the shape of space surfaces often changes smoothly, we propose a heuristic technique to fill the holes with proper depth value, which will be used to find correct color from another reference image during backward mapping step. By using the true depth value in our backward mapping algorithm, more accurate image may be produced.
