Super-resolution using neighbourhood regression with local structure prior

作者:

Highlights:

• A measure is proposed for extracting local structural similarity. For each patch, the local structure prior can yield a robust representation.

• An algorithm is developed for learning multiple local mappings. Different linear mappings are used simultaneously to reconstruct the desired image.

• A model is proposed that combines hierarchical similarity and local structure priors. This model yields more reasonable and reliable results than the existing methods based on clustering or regression alone.
