摘要： A method, system, computer program product, and computer system for processing video frames. Frames A and B of a pair of successive video frames each comprise blocks of pixels. Frame A is earlier in time than frame B. A connection state of each pixel in frame B relative to the pixels of frame A is determined. The connection state is a connected state or an unconnected state. Each block in frame B is classified as either unconnected or uni-connected. Uni-connected blocks in frame B satisfying a reclassification criteria are reclassified as being unconnected. Each unconnected block in frame B is categorized as being a P-block or an I-block. Values for the pixels of each I-block in frame B are calculated by spatial Interpolation based on values of nearest available neighbor pixels relative to each I-block. A residual error block for each I-block in frame B is generated.
摘要翻译：一种用于处理视频帧的方法，系统，计算机程序产品和计算机系统。一对连续视频帧的帧A和B各自包括像素块。帧A在时间上比帧B早。确定帧B中每个像素相对于帧A的像素的连接状态。连接状态是连接状态或未连接状态。帧B中的每个块被分类为未连接或单连接。满足重新分级标准的框架B中的单连接块被重新分类为未连接。帧B中的每个未连接的块被分类为P块或I块。基于相对于每个I块的最近可用相邻像素的值，通过空间插值来计算帧B中每个I块的像素的值。生成帧B中每个I块的残差错误块。

摘要： A method, computer program product, and computer system for processing video frames. A current frame is divided into M blocks that include at least two differently sized blocks. M is at least 9. Each block in the current frame is classified as being a motion block or an I-BLOCK. Overlapped block motion compensation (OBMC) is performed on each block of the M blocks according to a predetermined scan order. The block on which OBMC is being performed is denoted as a self block (270). The OBMC is performed on the self block (270) with respect to its neighbor blocks (271, 272, 273, 274). The neighbor blocks consist of nearest neighbor blocks of the self block. Performing OBMC on the self block includes generating a weighting window for the self block and for each of its neighbor blocks.
