The merit of both shift invariance and directionalselectivity enables the complex wavelet to overcome the artifacts in the discrete orthonormal wavelet denoising.
The new DFB can provide good directional and frequency selectivity.
新的方向滤波器组具有良好的方向和频率选择性。

Further more, we give an explanation of the intrinsic implication of the present method and our comprehension about directional orientational selectivity and preferred direction orientation.
