Abstract: A method and apparatus perform palette coding of a block of video data by initializing the palette or triplet palette or using a selected palette or triplet palette from a preceding image area for the beginning block of the current image area. The method receives input data associated with a current image area consisting of multiple blocks. For the beginning block, coding palette predictor is determined based on an initial palette or triplet palette or based on a selected palette or triplet palette associated with a selected block located at a location before the end of a preceding image area. For blocks of the current image area, palette coding is applied to the blocks, where at least one block uses the palette predictor for the beginning block as the palette predictor.

Abstract: A method for palette coding is disclosed. In an encoder side, the method determines whether a first block is coded using a palette coding mode or a non-palette coding. If the first block is coded using the non-palette coding mode, a first color table for the first block is derived based on one or more color tables associated with one or more previously processed blocks. If the first block is coded using the palette coding mode, the first color table is derived from the first block. A second block coded after the first block may use the first color table as a palette prediction. At the decoder side, if the current block is coded using the palette coding mode, a first color table based on a previous coded block is derived and the current block is decoded using a first color table as a palette predictor.

Abstract: Dynamic Hierarchical Empirical Bayes techniques and systems are described that are implemented to control output of digital content. In one example, a system identifies splitting variables included in data. An amount of loss is then determined for each of the identified splitting variables by the system using a loss function. Based on the determined amounts of loss, the system selects at least one splitting variable from the plurality of splitting variables that are to be used to partition data in a respective node, e.g., a parent node to form a plurality of child nodes. The system, for instance, may select the splitting variable that minimizes the cost, i.e., has the lowest amount of cost. The selected splitting variable is then employed by the system to generate at least one hierarchical level of the hierarchical structure of the statistical model by partitioning data from the parent node into respective child nodes.
