一种深度图的时域下采样编码及重建方法
Temporal subsampling based depth maps coding and the reconstruction method
摘要
Abstract
In order to improve the coding efficiency of a three‐dimensional video system , a depth temporal subsampling based coding method for the intermediate view is proposed . In this paper , the manner of how to discard depth frames is firstly determined . Then , those discarded depths are reconstructed utilizing temporal consistency and multiview correspondences . Finally , in order to further improve the quality of the reconstructed depth , the wiener filter is implemented on the reconstructed results . Filter coefficients and indicators for selecting the depth predictor should be transmitted to the decoder . Experimental results demonstrate that a maximum 0.229 dB and average 0.130 dB peak signal‐to noise ratio ( PSNR) gain could be achieved for the virtual view reconstructed by the decoder while maintaining the same coding bit rate ,and that the coding efficiency can be improved .关键词
