    • The present invention relates to a method of motion estimation for use in a device adapted to process a sequence of frames, a frame being divided into blocks of data samples. Said motion estimation method comprises a step of computing a residual error block associated with a motion vector candidate (MV) on the basis of a current block (cb) contained in a current frame (CF) and of a reference block (rb) contained in a reference frame (RF), said reference block having a same position in the reference frame as the current block has in the current frame. The motion vector candidate defines a relative position of a virtual block (vb) containing a first reference portion (rbp1) of the reference block with reference to said reference block. The residual error block is then computed from a first difference between data samples of the first reference portion and corresponding data samples of a first current portion (cbp1) of the current block, and a second difference between a prediction of data samples of a second reference portion (pred) of the virtual block, which is complementary to the first reference portion, and data samples of a second current portion (cbp2) of the current block, which is complementary to the first current portion.
    • 本发明涉及一种用于在适于处理帧序列的设备中使用的运动估计方法,帧被划分成数据样本块。 所述运动估计方法包括以下步骤:基于包含在当前帧(CF)中的当前块(cb)和包含在当前帧(CF)中的参考块(rb),计算与运动矢量候选(MV)相关联的残差误差块 参考帧(RF),所述参考块在当前帧中在当前帧中具有与参考帧中相同的位置。 运动矢量候选定义参考所述参考块的包含参考块的第一参考部分(rbp1)的虚拟块(vb)的相对位置。 然后根据第一参考部分的数据样本和当前块的第一当前部分(cbp1)的对应数据样本之间的第一个差异和第二个参考的数据样本的预测之间的第二个差值来计算剩余误差块 与第一参考部分互补的虚拟块的部分(pred)以及与第一当前部分互补的当前块的第二当前部分(cbp2)的数据样本。
