The Implementation and Application of Image Adaptive Dictionary Algorithm Based on Manifold

Abstract:

As an important field of image processing, image restoration has ever been a hot research topic. Our paper will focus on the adpative dictionary. We propose a novel improved adaptived dictionary learning algorithm. Utilizing the thoughts of manifold, for each atom in dictionry, we calculate the principal components of responding representaion errors as the tangent vector of the atom, which improves the representaion ability of dicitonary. Meanwhile, dictionary learned from the origin image is better at image denoising than adpative dictionary.
