However, the high computational complexity prevents it from real-time application. In this paper, a fast intra-view mode decision and inter-view prediction termination algorithm based on just noticeable distortion (JND) is proposed to speed up the search process of motion estimation (ME) and disparity estimation (DE). The basic idea of the method is to exploit JND threshold in mode prediction to make an early decision on the process of variable size ME and DE in MVC. We not only narrow down prediction mode size candidates, but also terminate the process of DE early. Experimental results demonstrate that the proposed algorithm is able to reduce the entire encoding time by 79.94% on average among different views, with negligible loss of coding efficiency.
