MEASUREMENT OF VIDEO IMAGE ACTION DUE TO DCT AND PREDICTIVE ERROR COEFFICIENT FILTERING

摘要

PROBLEM TO BE SOLVED: To reduce complexity on calculation in the case of calculating the action of the macroblock of a video picture. ;SOLUTION: A predictive error calculation is performed in a spatial frequency domain obtained by discrete cosine transform instead of performing a calculation about the macro block arranged on a source picture, in the case of calculating the action of the macrobloek of the video picture.;COPYRIGHT: (C)2001,JPO
