分解域 meaning in English

decomposition field

We have tested multi - resolution motion estimation ( mrme ) technique to achieve multi - frame compression in matlab
用小波分解域内运动估计方法进行多帧图像压缩。
In mrme , coding of intra - frame and inter - frame are done in wavelet decomposition domain . mrme costs much less time to perform motion estimation operation compared to block matching motion full search algorithm ( fsa )
该方法可保证帧内、帧间编码过程始终在小波分解域内进行，运动估计运算量比块匹配全搜索法小得多。
