( 2 ) a new texture classification algorithm based - on the lifting wavelet transform in suggested utilizing wavelets " perfect performance in spatial - frequency localization and the lifting wavelets " in - place operations. it computes the entropy values of the sub - frequency images disposed by the two - layers " lifting wavelet transform, and has merits of low feature dimensions, low computational cost and good capability
利用小波分析的時頻局域化特性以及提升小波的本位運算等優點，對紋理圖象進行提升小波分解，再對得到的高頻子圖繼續做第二層小波分解，然後以各頻率子圖的圖象熵作為圖象的紋理特徵進行紋理分類。 -
After the image lifting wavelet transformation, its coefficients have some characteristics, for example : the frequency compression characteristic, namely the primitive image energy majority of gathers to the low frequency sub - belt ; spatial compression characteristic, namely high frequency sub - belt energy majority of centralisms in primitive corresponding and so on image edge, outline position ; the coefficient distribution similarity, namely in the
經提升小波變換后，其系數具有如下特性:頻率壓縮特性，即原始圖像的能量大部分聚集到低頻子帶;空間壓縮特性，即高頻子帶的能量大部分集中在原始圖像的邊緣、輪廓等對應的位置;系數分佈相似性，即同一方向上各級子帶系數幅值分佈大體一致。
