Abstract: Highlights•Design a diffusion-based SISR method to restore details from low-resolution images.•Overcome issues in deep SISR methods, reducing high-frequency loss and enhancing image quality.•Capture local details by merging edge features to restore high-frequency information.•Optimize the noise prediction network to enhance edge synthesis using fused features.•Evaluation on DIV2K and benchmarks confirms EFD’s superior performance.
