Method and apparatus for cost calculation in decimal motion estimation

摘要

A method and an apparatus for cost calculation in decimal motion estimation are provided. The method comprises the following steps. Firstly, perform interpolation on a current block to get an interpolation result of a position corresponding to a decimal motion vector. Secondly, calculate a cost according to data at integer point positions of a reference frame corresponding to the current block and the decimal motion vector, and according to the interpolation result.
