3D Holoscopic Images Coding Scheme Based on Viewpoint Image Rendering

3D holoscopic imaging can provide immersive 3D viewing experiences, which is considered to be a promising 3D acquisition and display solution. However, in order to proper storage and delivery such particular type of image, efficient coding schemes are of great importance. Therefore, in this paper, we propose a new coding scheme based on viewpoint image rendering. All the viewpoint images are rendered firstly from the 3D holoscopic contents. The total rendered viewpoint images are then arranged into a video sequence. HEVC inter coding method is utilized to remove the redundancy among the rendered viewpoint images. Experimental results show that the proposed coding scheme can achieve average 2.70 dB quality improvements for holoscopic images compared to HEVC intra standard.
