In this paper, we propose a depth-wise flexible block processing method called split unit coding order (SUCO) for video coding. Conventionally, block-based image and video compression frameworks always apply raster scans to process blocks in order from left to right. Owing to the fixed coding order, the available information for prediction in the coding blocks is limited to adjacent blocks on the left and top. To address the limitations of block-based images and video compression frameworks, the proposed SUCO provides more flexibility in handling coding block sequences than predicted on the left and top, and thus coding blocks can take advantage of adjacent right information, such as reconstructed pixels and motion information. The flexibility is achieved by depth-wise signaling of preferred coding order for the given partitions. The experiment results demonstrate that the proposed SUCO can effectively improve the coding efficiency of both intra and inter prediction in the latest video coding standards.

视频压缩的深度分割单元编码顺序
在本文中,我们提出了一种深度灵活的块处理方法,称为分割单元编码顺序 (SUCO),用于视频编码。传统上,基于块的图像和视频压缩框架总是应用光栅扫描以从左到右的顺序处理块。由于固定的编码顺序,编码块中可用于预测的信息仅限于左侧和顶部的相邻块。为了解决基于块的图像和视频压缩框架的局限性,所提出的 SUCO 在处理编码块序列方面提供了比左侧和顶部预测的更大的灵活性,因此编码块可以利用相邻的右侧信息,例如重建像素和运动信息。灵活性是通过给定分区的优选编码顺序的深度信号来实现的。
