    • [00108] A method and apparatus are disclosed herein for spatial sparsity induced temporal prediction. In one embodiment, the method comprises: performing motion compensation to generate a first motion compensated prediction using a first block from a previously coded frame; generating a second motion compensated prediction for a second block to be coded from the first motion compensated prediction using a plurality of predictions in the spatial domain, including generating each of the plurality of predictions by generating block transform coefficients for the first block using a transform, generating predicted transform coefficients of the second block to be coded using the block transform coefficients, and performing an inverse transform on the predicted transform coefficients to create the second motion compensated prediction in the pixel domain; subtracting the second motion compensated prediction from a block in a current frame to produce a residual frame; and coding the residual frame.
    • 这里公开了一种用于空间稀疏度引起的时间预测的方法和设备。 在一个实施例中,该方法包括:执行运动补偿以使用来自先前编码帧的第一块产生第一运动补偿预测; 使用空间域中的多个预测来从第一运动补偿预测生成要编码的第二块的第二运动补偿预测,包括通过使用变换生成第一块的块变换系数来生成多个预测中的每一个, 使用所述块变换系数来生成要编码的所述第二块的预测变换系数,并且对所述预测变换系数执行逆变换以在所述像素域中创建所述第二运动补偿预测; 从当前帧的块中减去第二运动补偿预测以产生残余帧; 并对残留帧进行编码。
