论文摘要
包含丰富信息的元素图像和视频需要大量的数据存储和高传输成本。虽然对元素图像编码进行了很多研究，但对元素视频编码的研究非常有限。我们通过查看射线空间域中的问题而不是在常规像素域中的问题来研究元素视频编码的运动补偿。在这里，我们为射线空间运动的两个子速率，即整数射线空间运动和分数射线空间运动开发了一个新型的运动补偿方案。拟议的新方案设计了光场运动补偿预测，使其可以轻松地集成到众所周知的视频编码技术中，例如HEVC。与现有方法相比，实验结果显示出显着的压缩效率，平均增益为19.63％，峰值增长率为29.1％。
Plenoptic images and videos bearing rich information demand a tremendous amount of data storage and high transmission cost. While there has been much study on plenoptic image coding, investigations into plenoptic video coding have been very limited. We investigate the motion compensation for plenoptic video coding from a slightly different perspective by looking at the problem in the ray-space domain instead of in the conventional pixel domain. Here, we develop a novel motion compensation scheme for lenslet video under two sub-cases of ray-space motion, that is, integer ray-space motion and fractional ray-space motion. The proposed new scheme of light field motion-compensated prediction is designed such that it can be easily integrated into well-known video coding techniques such as HEVC. Experimental results compared to relevant existing methods have shown remarkable compression efficiency with an average gain of 19.63% and a peak gain of 29.1%.
