Context-aware single image super-resolution using sparse representation and cross-scale similarity

作者：

Highlights：

• A “denoised” sparse coding model is used to establish a primitive structure prior.

• Context is utilized to determine where the example-based method should be used.

• The proposed method gives the user flexibility in specifying the exemplar images.
