In this paper, we present a locally adaptive regularized super-resolution model for images with mixed noise and outliers. The proposed method adaptively assigns the local norms in the data fidelity term of the regularized model. Specifically, it determines different norm values for different pixel locations, according to the impulse noise and motion outlier detection results. The L-1 norm is employed for pixels with impulse noise and motion outliers, and the L-2 norm is used for the other pixels. In order to balance the difference in the constraint strength between the L-1 norm and the L-2 norm, a strategy to adaptively estimate a weighted parameter is put forward. The experimental results confirm the superiority of the proposed method for different images with mixed noise and outliers. (c) 2014 Elsevier B.V. All rights reserved.
