摘要

This article presents a performance analysis of Versatile Video Coding (VVC) intra-frame prediction. VVC is the next generation of video coding standards, which has been developed to supply the demand of upcoming video applications. VVC brings several innovations and enhancements for the intra-frame prediction to improve the encoding efficiency. These improvements comprise larger block sizes, more flexible block partitioning, more angular intra-frame prediction modes, multiple transform selection, non-separable secondary transform, among others. This article provides a detailed description of these tools, discussing how they work together in the intraframe coding flow to raise the compression performance. Moreover, this article presents encoding complexity, encoding usage distribution, and rate-distortion-complexity analyses of the intra-frame prediction tools over different quantization scenarios. Based on these analyses, this article provides support for future works focusing on VVC intra-frame coding, including complexity reduction, complexity control, and real-time hardware design.
