Multiview video coding (MVC) adopts ex haustive variable size mode decision and multiple reference frames selection to achieve s ignificantly high compression efficiency at each macroblock.However,the technology increases the computational complexity of MVC encoders tremendously.To solve this problem,a n ew fast macroblock mode selection algorithm of MVC based on visual perception is propose d by utilizing the conception of just noticeable difference (JND).It builds the correlation of MVC macroblock mode se lection with JND considering human visual perceptual properties to gain the threshold to optimize the process of va riable size mode selection in MVC.According to the relation between the threshold and the JND of the current macroblock,th e proposed algorithm can adaptively decrease the time of macroblock partition modes selecting,and then reduce the time of s earching for the best reference frame index and the best reference direction for each macroblock.That is to say,it can decrease co mplexity of each macroblock to improve the efficiency.Experimental results show that the proposed mode selection algorithm can reduce 76.00% of the encoding time averagely compared with JMVC and almost maintain the same coding e fficiency, while showing the adaptability to various video contents,camera arrangements and motion properties of scenes.
