Japanese Patent JP4625240

Kind Code:

B2

Abstract:

Various techniques and tools for approximate bicubic filtering are described. 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, a video decoder uses approximate bicubic filtering when computing pixel values at quarter-pixel positions.
