PROBLEM TO BE SOLVED: To provide various techniques and tools for approximate bicubic filtering. SOLUTION: For example, during motion estimation and compensation, a video encoder uses approximate bicubic filtering when computing pixel values at quarter-pixel positions in reference video frames. Or, during motion compensation, the video decoder uses approximate bicubic filtering when computing pixel values at quarter-pixel positions. COPYRIGHT: (C)2004,JPO
