Saliency adaptive super-resolution image reconstruction

A saliency-based approach is proposed in this paper to perform super-resolution image reconstruction, with the aim to produce a higher-resolution image based on its low-resolution counterparts. The proposed approach adaptively adjusts the degree of regularization using the saliency measure of the local content of the image. Furthermore, a gradient-based criterion is proposed to measure the saliency of the image. Experiments are conducted to demonstrate the superior performance of the proposed approach.
