Synergizing frequency domain and texture-aware implicit module for MRI arbitrary-scale super-resolution

Xinyue Tu, Guangyuan Li, Yuanxing Liu

Abstract: Highlights•We propose a novel method using frequency domain and texture information for MRI arbitrary-scale SR.•We design a frequency domain branch to fully exploit frequency-domain information.•We design a texture-aware implicit module to restore detailed information within the MR images.
