View synthesis method capable of depth mismatching checking and depth error compensation

摘要

A view synthesis method of depth mismatching checking and depth error compensation, wherein, input left and right maps are warped in a processor to perform view synthesis, comprising following steps: when a present pixel moves to a position of a target pixel after warping, compute respectively pixel displacement amounts for said present pixel to move to said target pixel in said left and said right maps, to figure out coordinate of said target pixel; determine if depth value of the present pixel is greater than that of said target pixel, if an answer is positive, determine if depth value of said present pixel matches that of coordinate adjacent to said target pixel; and if answer is negative, set depth value of said target pixel to a hole; otherwise, cover said target pixel with pixel value of said present pixel, hereby completing refining even minute errors.

1. A view synthesis method capable of depth mismatching checking and depth error compensation, wherein, inputting a left map and a right map are warped in a processor to perform view synthesis, comprising following steps:
(a) when a present pixel moves to a position of a target pixel after warping, compute respectively pixel displacement amounts for said present pixel moving to said target pixel in said left map and said right map, to figure out coordinate of said target pixel; (b) determine if depth value of said present pixel is greater than that of said target pixel, in case answer is negative, return to step (a) to compute pixel displacement amount for next said present pixel; (c) determine if depth value of said present pixel matches that of coordinate adjacent to said target pixel; and (d) in case said answer is negative for step (b), set depth value of said target pixel as a hole; otherwise, cover said target pixel with pixel value of said present pixel.
