摘要： An image coding method and apparatus and an image decoding method and apparatus are provided by the present document. The image coding method includes: implementing matching coding for pixels of an input video image to obtain one or more matching relationship parameters, herein the matching relationship parameters are parameters used in a process of constructing predicted values and/or reconstructed values of the pixels in the image; mapping the matching relationship parameters to obtain mapped values of the matching relationship parameters; and performing entropy coding on the mapped values of the matching relationship parameters. The present document addresses the problem existing in the conventional art which is caused by the direct implementation of entropy coding for matching relationship parameters and achieves a good data compression effect through entropy coding.

摘要： The present invention provides an image compression method and device. When a coding block is coded, first, second and third reconstructed reference pixel sample sets, of which position labels are not intersected, are searched to obtain one or more optimal fixed-width variable-length pixel sample matching strings according to a preset evaluation criterion. Each matching string is represented by a matching distance and a matching length. For a sample of which a match is not found, a pseudo matching sample is calculated from an adjacent sample. Matching string searching may be performed in a pixel component plane only, and may also be performed in a three-component individually intersected pixel space in a packed format. Optional quantization or transformation-quantization coding, predictive coding, differential coding and entropy coding are further executed on the matching distance, the matching length and a matching residual. Multiple sample division manners and arrangement manners may be adopted for matching, and optimal ones are selected from them. For the same Coding Unit (CU), conventional-prediction-based hybrid coding is simultaneously performed, and an optimal result is selected finally.

摘要： Techniques for encoding, decoding, and extracting one or more bitstreams to form one or more sub-bitstreams are described. In one example aspect, a method for video or picture processing includes partitioning a picture into one or more tiles and generating one or more bitstreams using one or more configurations based on the one or more tiles. Generating each of the one or more bitstreams includes partitioning each of the one or more tiles into one or more slices, and performing, for each slice among the one or more slices a first encoding step to encode a tile identifier in a header of the slice, and a second encoding step to encode, in the header of the slice, a second address of the slice that indicates a location of the slice in the tile.
