Missing data super-resolution using non-local and statistical priors

Abstract : We here address the super-resolution of a high-resolution im- age involving missing data given that a low-resolution im- age of the same scene is available. This is a typical issue in the remote sensing of geophysical parameters from differ- ent spaceborne sensors. Such super-resolution application in- volves large downscaling factor (typically from 10 to 20) and the super-resolution model should account for both texture patterns and specific statistical features, especially the spec- tral and non-Gaussian features. In this context, we propose a novel non-local approach and formally states the solution as the joint minimization of several projection constraints. We illustrate the relevance of the proposed model on real ocean remote sensing data, namely sea surface temperature fields, as well on visual textures.
