Abstract

Abstract:

Due to the variability in virtual visibility,the imprecise depth image and the inaccurate calculation,matching errors may occur in the virtual views synthesized by DIBR ( Depth Image-Based Rendering) techniques. In order to solve this problem,a matching error correction algorithm named Zero-Cross Correction ( ZCC) is proposed based on the order matching constraint. ZCC determines the matching error region by analyzing the mapping
relations between the pixel points in the destination image and the corresponding matching points in the reference image,and it assigns the matching points of all points in the matching error region to the matching points of the starting point in the same region,thus successfully implementing the correction of matching error. Experimental results indicate that the proposed algorithm is effective in eliminating matching errors and that it can be applied as an additional error detection and correction algorithm to the postprocessing of novel views generated by DIBR because it is totally independent of the 3D image wraping in DIBR.

Key words: stereoscopic TV, depth image-based rendering, matching error correction, 3D image warping
