    • Methods and apparatus are provided for adaptive residual updating of template matching prediction for video encoding and decoding. In one embodiment, an apparatus and method encodes picture data for at least a block in a picture using template matching prediction, wherein the template matching prediction involves selecting from among a plurality of residual updating schemes for use in encoding the block (715, 740, 750, 775, 935, 945). In another embodiment, an apparatus and method encodes a block in a picture using template matching prediction, wherein the template matching prediction involves partitioning the block into a plurality of sub-blocks (720, 725, 730, 735, 915, 920, 925, 930, 1115, 1120, 1125, 1130, 1150, 1155, 1160, 1165), and applying a transform to a residual of a particular sub-block (740, 750, 935, 945, 1135, 1175) from among the plurality of sub-blocks subsequent to searching for a prediction for the particular sub-block block and prior to completion of processing of the block with respect to the template matching prediction.
    • 提供了用于视频编码和解码的模板匹配预测的自适应残差更新的方法和装置。 在一个实施例中,一种装置和方法使用模板匹配预测编码图片中的至少一个块的图像数据,其中模板匹配预测涉及从用于编码块的多个残留更新方案中进行选择(715,740, 750,775,935,945)。 在另一个实施例中,一种装置和方法使用模板匹配预测对图片中的块进行编码,其中模板匹配预测涉及将块划分成多个子块 930,1115,1120,1125,1130,1150,1155,1160,1165),并且对多个子块中的特定子块(740,750,935,945,1135,1175)的残差应用变换 在针对特定子块块搜索预测之后,以及在关于模板匹配预测的块的处理完成之前的子块。
