METHOD AND APPARATUS FOR COST CALCULATION IN DECIMAL MOTION ESTIMATION

摘要

PROBLEM TO BE SOLVED: To calculate a cost of a decimal motion vector with high compression quality and low computing amount by effectively calculating multiple block sizes.;SOLUTION: The method comprises the following steps. Firstly, perform interpolation on a current block to get an interpolation result of a position corresponding to the decimal motion vector. Secondly, calculate the 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.;COPYRIGHT: (C)2007,JPO&INPIT
