A wavelet-domain algorithm for denoising in the presence of noise outliers
Michalis E. Zervakis, V. Sundararajan, Keshab K. Parhi · 2002
A wavelet domain robust denoising algorithm is presented, which efficiently removes both Gaussian as well as Gaussian mixed with impulse noise. Several wavelet domain operators are developed which help in the denoising process. The superiority of the new algorithm is firmly established by simulation over a variety of images.
