Abstract:Image restoration via Alternating Direction Method of Multipliers (ADMM) has gained large interest within the last decade. Solving standard problems of Gaussian and Poisson noise, the set of ‘Total Variation’ (TV) based regularizers proved to be efficient and versatile. In the last few years the ‘Total Generalized Variation’ (TGV) approach combined TV regularizers of different orders adaptively to better suit local regions in the image. This improved the technique significantly. The approach solved the stairca… Show more
