In order to relief the virtual view′s quality reduction induced by th e transmission distortion,we propose a macro block level significance model applied to both depth map and texture ma p.The model contains two main parts:firstly,by considering the temporal and spatial correlation of the compr ession structure and the distortion diffusion due to lost packets,we propose a recursive transmission distortion model;secondly,we discuss the relationship between synthesis distortion and both depth-error and texture-err or induced distortions.A low-complexity significance model based on the analysis of synthesis distortion is proposed.Experimental results show that compared with random packet loss,the peak signal to noise ratio (PSNR) of the v irtual view could be increased dramatically(up to 15.65dB at 20% packet loss rate),and the subjective quality is close to the und istorted transmission condition.
