HST: Hierarchical Swin Transformer for Compressed Image Super-resolution. (arXiv:2208.09885v1 [cs.CV])

Compressed Image Super-resolution has achieved great attention in recent
years, where images are degraded with compression artifacts and low-resolution
artifacts. Since the complex hybrid distortions, it is hard to restore the
distorted image with the simple cooperation of super-resolution and compression
artifacts removing. In this paper, we take a step forward to propose the
Hierarchical Swin Transformer (HST) network to restore the low-resolution
compressed image, which jointly captures the hierarchical feature
representations and enhances each-scale representation with Swin transformer,
respectively. …
