Compared with traditional symmetric 3d wavelet transform, asymmetric 3d wavelet transform can more efficiently remove the correlation between the adjacent bands.
与传统的对称三维小波变换相比，非对称的三维小波变换能够更有效地去除相邻谱段间的冗余。
The algorithm, which multiplies the corresponding wavelet coefficients of adjacent fine scales, enhances the feature of discontinuity point of signals and inhibits the effect of noise signals.
该算法将相邻两个细尺度层上的小波变换系数对应相乘，从而增强了信号在突变点处的特征并抑制了噪声的影响。
