摘要：

Translation invariant (TI) single wavelet denoising was dt,eloped by Coifman and Donoho, and they show that TI is better than non-TI single wavelet denoising. On the other hand, Strela et al. have found that non-TI multiwavelet denoising gi,es better results than non-TI single wavelets. In this correspondence, we extend Coifman;ind Donoho's TI single wavelet denoising scheme to multiwavelets, Experimental results show that TI multiwavelet denoising is better than the single case for soft thresholding.
