Radial Scanning Scheme for Massively Parallel Video Coding

摘要

This article presents a scheme of image blocks scanning, called radial scanning, that enables massive parallelization of video compression and decompression. The proposed scheme enables parallel processing of image blocks when still using the context-based coding paradigm. Compared to other competitive schemes of image blocks scanning, the proposed scheme allows higher degree of computations parallelization in a video codec. Due to using the context-based coding the proposed scheme does not negatively affect the compression performance of a video encoder.
