Jian Hu · Jisuanji yingyong yanjiu · 2002
This paper introduces a new motion estimation algorithm,the DCTbased motion estimation(DXTME)utilizing the sinusoidal orthogonal principles to estimate displacements of moving objects in transform domain.This new algorithm is extended from the DCT pseudophase techniques of 1D signals.In addition to its robustness in a noisy environment,the DXTME has a lower computational complexity compared to BKMME algorithm.Furthermore,its ability to estimate motion completely in DCT domain makes the fully DCTbased motion compensated video coder structure possible,which results in a higher system throughput.
