METHOD AND APPARATUS FOR CALCULATING COST FUNCTIONS AND INTERPOLATION METHOD THEREOF |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide an interpolation method suitable for decimal motion estimation that can reduce the memory bandwidth needed for interpolation filtering. <P>SOLUTION: The interpolation method comprises: a step of dividing a data range needed by an interpolation filtering process into a loaded range and a speculation range; a step of loading data in the loaded range; a step of generating the data in the speculation range based on the data in the loaded range; and a step of using the data range as input data to perform the interpolation filtering process. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
