Image Denoising Based on Hybrid Fourier and Neighborhood Wavelet Coefficients

Jun Cheng, Songli Lei
Image denoising is a classical topic and a difficult problem in the field of image processing. Fourier transform can effectively sparsely represent the smoothing texture part of the image, but can’t effectively represent mutations in the image. The wavelet transform can sparsely represent sharply changing...
