摘要：
Transform-domain image denoising methods assume that the original signal can be sparsely represented in the transform domain, but none of the orthogonal transforms can achieve sparse representation for all images. Proposed is a hybrid Fourier-wavelet denoising method to overcome this shortcoming. Experimental results show that the proposed algorithm improves denoising performance efficiently.
