Fast Mode Decision Algorithm for Multiview Video Coding Based on Binocular Just Noticeable Difference

Although multiview video and its applications are becoming increasingly prevalent, there have been very limited researches on multiview video coding (MVC) specially combined with human visual system. To reduce computational complexity of MVC, a fast mode decision algorithm for MVC based on binocular just noticeable difference is proposed in this paper. A binocular just noticeable difference model that describes the sensitivity of the human visual system to luminance changes is used. A solution is found within establishing an optimization framework with a threshold obtained from the relationship between the binocular just noticeable difference values and the inter mode decision. It is able to early terminate the unnecessary mode decision in the imperceptible changed regions for achieving time saving. Experimental results show that the proposed algorithm can significantly reduce the MVC time with negligible bit rate increment.
