WebSep 23, 2014 · Meanwhile, we put forward a novel and effective algorithm called augmented Lagrange multipliers to exactly solve the problem. For mixed Gaussian-impulse noise removal, we regard it as the problem of matrix completion from corrupted samplings, and restore the noisy image following an impulse-detecting procedure. WebSep 25, 2010 · In recent years, many algorithms have been proposed to solve the LRMR optimization models, such as the augmented Lagrange multiplier method by Lin et al. …
