Depth video coding based on motion information sharing prediction for mixed resolution 3D video

Three-dimensional (3D) video has evolved and spread rapidly in recent years. In the 3D video, since a depth component and corresponding texture component have similar object movement, there is a redundancy in their motion information. To remove this motion redundancy, motion information sharing from texture to depth is useful in 3D video coding. In this paper, we propose a method for motion information sharing prediction (MISP) for use in mixed resolution 3D video coding. The MISP is applied for any types of macroblock even it is coded as intra mode. Experimental results show that the proposed MISP reduces the bit rate for depth by up to 7.3%.
