Disparity compensation based 3D holoscopic image coding using HEVC

3D holoscopic image can provide true 3D content by reproducing the light rays of the 3D scene and is regarded as a promising technique for future 3D TV. Disparity information is paramount intrinsic characteristic of the 3D holoscopic image. In this paper, a disparity compensation based 3D holoscopic image coding algorithm using HEVC is put forward. In order to drive an authentic disparity, we expand the available area outwards in the disparity matching process instead of dividing the current coding block into four parts. Experimental results demonstrate that the proposed method can obtain considerable gains over original HEVC intra-prediction and the classical TMP algorithm with acceptable complexity increasing compared to original HEVC standard.
