    摘要： System and method embodiments for image coding are disclosed. In an embodiment, a method in a data processing system for image encoding includes determining a sparsity constraint according to a dimension of an input image signal. The method also includes iteratively determining a plurality of approximations to the input image signal. Each iteration provides an approximation of the input image signal. Each approximation includes a set of dictionary element indices and coefficients. The dictionary is an over-complete dictionary. Iterations of the determining step are terminated when a number of iterations is equal to the sparsity constraint. The method also includes selecting one of the plurality of approximations according to a minimum rate-distortion cost. The method also includes determining an encoded image signal according to non-zero coefficients and corresponding indices for each non-zero coefficient in the selected approximation.

    摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing intra coding predictions. An intra-coding process applied to pixels in a frame of media is determined. The intra-coding process is determined whether to corresponding to at least one of most probable modes. In response to determining the intra-coding process does not correspond to the at least one of the most probable modes, four angular prediction modes are extracted from a list of prediction modes. A set of candidates based on the four angular prediction modes are determined. A pre-defined order of the set of candidates is determined, wherein each candidate mode of the set of candidate modes is included in a ranked order and signaled with a particular fixed length coding, and wherein a length of the particular fixed length coding increases based on the pre-defined order of the set of candidate modes.
