Texture enhancement for improving single-image super-resolution performance

作者：

Highlights：

• This paper addresses a key remaining issue, texture SR, which is yet unresolved.

• Patch-based texture synthesis is performed by using a LR texture layer.

• A HR texture patch is synthesized based on both AR and reconstruction models.

• The proposed algorithm provides realistic SR images with sharp and fine textures.
