Abstract While low-resolution face images are reconstructed via deep learning based super-resolution reconstruction method, some problems emerge, such as blurred reconstructed images and obvious difference between reconstructed images and real images. Aiming at these problems, a face super-resolution reconstruction method fusing reference image is proposed to reconstruct low-resolution human face images effectively. The multi-scale features of reference image are extracted by reference image feature extraction subnet to retain the detail information of key parts and remove the redundant information, such as facial contour and facial expression. Based on the multi-scale features of reference image, the step-by-step super-resolution main network fills the features to low-resolution face image step by step. Finally, the high-resolution face image is generated. Experiments on datasets indicate that the proposed method reconstructs low-resolution face images effectively with good robustness.
