    • 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。

    • Various implementations are described. Several implementations relate to determining, providing, or using a depth value representative of an entire coding partition. According to a general aspect, a first portion of an image is encoded using a first-portion motion vector that is associated with the first portion and is not associated with other portions of the image. The first portion has a first size. A first-portion depth value is determined that provides depth information for the entire first portion and not for other portions. A second portion of an image is encoded using a second-portion motion vector that is associated with the second portion and is not associated with other portions of the image. The second portion has a second size that is different from the first size. A second-portion depth value is determined that provides depth information for the entire second portion and not for other portions.
    • 描述各种实施方式。 几个实现涉及确定,提供或使用代表整个编码分区的深度值。 根据一般方面,使用与第一部分相关联并且不与图像的其他部分相关联的第一部分运动矢量对图像的第一部分进行编码。 第一部分具有第一个大小。 确定第一部分深度值,其为整个第一部分提供深度信息,而不为其他部分提供深度信息。 使用与第二部分相关联并且不与图像的其他部分相关联的第二部分运动矢量对图像的第二部分进行编码。 第二部分具有与第一尺寸不同的第二尺寸。 确定提供整个第二部分的深度信息而不是其它部分的第二部分深度值。
