    • The invention relates to a method for determining for a high layer macroblock that uses inter-layer prediction a partitioning of the macroblock in partitions. It comprises the following steps: - dividing the high layer macroblock in non-overlapping high layer blocks of a predefined size; - determining a corresponding base layer pixel for one pixel, called reference pixel, of each high layer block; - identifying, for each reference pixel, a base layer macroblock to which the corresponding base layer pixel belongs, a base layer partition to which the corresponding base layer pixel belongs in the identified base layer macroblock, a base layer sub-partition to which the corresponding base layer pixel belongs in the identified base layer partition if the sub-partition exists; - deriving, for each of the high layer block, a single value, called PartInfo value; and - determining a partitioning of the high layer macroblock in macroblock partitions by comparing between them the PartInfo values associated with each of the high layer blocks.
    • 本发明涉及一种用于确定高层宏块的方法,该高层宏块使用层间预测来分割宏块中的分区。 它包括以下步骤: - 在预定义大小的非重叠高层块中划分高层宏块; - 确定每个高层块的一个像素(称为参考像素)的相应基本层像素; - 对于每个参考像素,识别对应的基本层像素所属的基本层宏块,相应的基本层像素属于所识别的基本宏块中的基本层分区,对应的基本层子分区 如果子分区存在,则基层像素属于所识别的基层分区; - 为每个高层块导出一个称为PartInfo值的单个值; 以及 - 通过在它们之间比较与每个所述高层块相关联的PartInfo值来确定宏块分区中的高层宏块的划分。

    • The invention relates to a method for reconstructing a picture that is part of a sequence of pictures, from coded digital data, representative of said current picture. It comprises the following steps: - construct (30, 34, 32, 36), for each picture block, first and second prediction blocks (from a first picture (h) and a second picture (I2) previously reconstructed, and - calculate (38), for each block, a confidence value representative of the proximity between the visual content of the first predictive block and the visual content of the second predictive block, and - reconstruct each block: - from a part of said coded digital data representative of said block and initial auxiliary data calculated from the first and second predictive blocks if the block confidence measurement is greater than a predetermined threshold, and - from other data if the confidence measurement is less than or equal to the predefined threshold.
    • 本发明涉及一种用于从代表所述当前图像的编码数字数据重建作为图像序列的一部分的图像的方法。 它包括以下步骤: - 为每个图像块构建(30,34,32,36)第一和第二预测块(来自先前重构的第一图像(h)和第二图像(I2),以及 - 计算( 38),对于每个块,表示第一预测块的视觉内容与第二预测块的可视内容之间的接近度的置信度值,并且 - 重建每个块: - 从代表 如果所述块置信度测量值大于预定阈值,则从所述第一预测块和所述第二预测块计算的所述块和初始辅助数据,以及 - 如果所述置信度测量小于或等于所述预定阈值,则从其他数据计算。
