ABSTRACT:
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.
