多视角分布式视频编码中基于置信度的时空边信息融合
TEMPORAL AND SPATIAL SIDE INFORMATION FUSION BASED ON CONFIDENCE LEVEL IN MULTI-VIEW DISTRIBUTED VIDEO CODING
摘要
Abstract
In current side information (SI)generation methods for multi-view distributed video coding (MDVC),the fusion of temporal and spatial SI fails to effectively select and extract the reliable parts of two SI.To address this issue,we propose a confidence level-based temporal and spatial SI fusion method.The method utilises the reliability mask of temporal and the spatial SI as well as spatiotemporal confidence mask to obtain the temporal and spatial fusion mask;then it uses fusion mask to select the optimal pixels from temporal and spatial SI for generating final fusion SI.Experimental results show that,under the condition of same bit rate,the peak signal to noise ratio (PSNR) obtained by this fusion method gains the improvement up to 0.79 dB than the temporal-leading fusion method,and the improvement up to 0.58 dB compared with the temporal-spatial compensating fusion mask.In addition,the reconstructed frame obtained can effectively preserve the details of the original image.关键词
