Decompose image into subbands (undecimated wavelet), denoise, and recompose again. fh = decomp_reconst_wavelet(im,Nsc,daub_order,block,noise,parent,covariance,optim,sig) im : image Nsc: Number of scales daub_order: Order of the daubec

广义交义验证的去噪程序包，能够对一维和二维的信号及图像进行处理-PiefLab is a library of Matlab algorithms for wavelet noise reduction PiefLab has several routines for: 1) Wavelet transforms: fast and undecimated, (bi)orthogonal, 1D, 2D. Special attention was paid to fast implementa

The most widely used transform for image fusion at multi scale is Wavelet Transform since it minimizes structural distortions. But, wavelet transform suffers lack of shift invariance & poor directionality. These disadvantages are overcome by
