Cross-plane chroma enhancement for SHVC Inter-Layer Prediction

摘要

This paper proposes a cross-plane chroma enhancement (CPCE) scheme to enhance the chroma planes of the inter layer reference (ILR) pictures for the Scalable extensions of HEVC (SHVC), the on-going scalable video coding project in JCT-VC. The CPCE scheme restores the blurred edges and textures in the chroma planes using the corresponding information from the luma plane. Experimental results under the SHVC common test conditions show that the average BD-rate reductions for the Cb and Cr chroma planes are as much as −7.5% and −8.5%, respectively, when compared with SHM-1.0.
