Abstract: Highlights•A reference-based texture enhancement network for single image SR is proposed.•A multi-scale texture enhancement module is designed to supplement and enhance the texture details.•An efficient mixed attention module is constructed to improve the feature learning ability of network.•Extensive experiments verify that the proposed network outperforms SOTA networks.
