METHODS FOR ENCODING AND DECODING VIDEO USING AN ADAPTIVE FILTERING PROCESS

摘要

Recent video coding schemes supports post image filtering process of the reconstructed image samples in additional to block edge filtering process. The filtering processes can be adapted on a block by block basis based on the spatial activity measurement of the block of image samples. The current invention provides methods and apparatuses to improve the adaptability of these filtering processes by adapting the filtering processes based on the prediction mode, transform sizes and quantization matrixes used for the reconstruction of a block of image samples. The benefits of the current invention are in the form of improving picture quality.
