Document Type and Number:
Japanese Patent JP5547301
Kind Code:
B2
Abstract:
High-fidelity video coding nowadays tends to adopt the RGB coding for directly reducing RGB inter-color redundancy without color space conversion. A known method uses a blockbased inter-color compensation algorithm for removing inter-color redundancy on RGB color planes by defining the correlation between color planes within each coding block as a linear model of slope and offset parameters, codes the base plane block and then predicts the other two color blocks from the base plane block. However, for most coding blocks the texture within a component block varies quite much. A new method for improved video coding uses adaptive segmentation of the base color component block, corresponding segmentation of the other color component blocks and individual slope and offset parameters for predicting each segment.
