摘要
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-colour compensation algorithm for removing inter-colour redundancy on RGB colour planes by defining the correlation between colour 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 colour 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 colour component block, corresponding segmentation of the other colour component blocks and individual slope and offset parameters for predicting each segment.
