VSR-Transformer

By Jiezhang Cao, Yawei Li, Kai Zhang, Luc Van Gool

This paper proposes a new Transformer for video super-resolution (called VSR-Transformer). Our VSR-Transformer block contains a spatial-temporal convolutional self-attention layer and a bidirectionaloptical flow-based feed-forward layer. Our VSR-Transformer is able to improve the performance of VSR. This repository is the official implementation of "Video Super-Resolution Transformer".
