Method and apparatus for video encoding with adjusting offsets based on pixel classification method and apparatus for video decoding with adjusting offsets based on pixel classification

摘要

The present invention proposes a video encoding method and apparatus, a video decoding method, and an apparatus thereof for generating a reconstructed image with a minimum error from an original image. According to the present invention, the offset merging information of the current block is parsed from the received bit stream, the offset type and offset values of the offset parameters of the current block are restored based on the offset merging information, the edge type of the current block indicated by the offset type Or an offset value corresponding to an edge class or a pixel value band of a reconstructed pixel determined based on a pixel value band type is selected from offset values and the pixel value of the reconstructed pixel is adjusted by an offset.
