Abstract

Sparse signal processing appears to be an emerging technology having certain application areas like denoising, deblurring, inpainting, etc. The dictionaries used in sparse signal processing are of much importance as they hold the basic patterns to retrieve the original image. A wide range of complete and overcomplete dictionaries are used for reconstruction of signals in the presence of noise. But no comparative study of these dictionaries is available in the literature till now for indexing their performance. Present work is devoted to carry out such a comparative study which would help in indexing the performance and effectiveness of the dictionaries in sparse signal reconstruction to reduce speckle noise. The results have been compared and analyzed with a set of standard test images.
