Abstract:
Methods and apparatus for facilitating motion estimation in video processing are provided. In one embodiment, search block is defined within one frame. A relative location of a corresponding block in another frame with respect to the search block is determined based on comparative searching at a predetermined granularity to produce a motion vector for the search block with a first precision. Correlation values are determined with respect to the search block for the corresponding block and for one block or more blocks defined at relative locations of less than the predetermined granularity with respect to the corresponding block in different directions. A refined motion vector for the search block with a second higher precision is determined based on the relative location of the block having a selected correlation value that is selected from among the determined correlation values.
