Abstract: Super resolution image restoration technology is a hot field of image processing in the field of video surveillance, image processing, forensic analysis, with a wide range of application requirements. In recent years, the rapid development of deep learning in the field of multimedia processing, deep learning based super-resolution images restoration has gradually become a mainstream technology. This paper reviews the existing deep learning based image super-resolution restoration work. In terms of network type, network structure, and training methods, the advantages and disadvantages of the prior art are analyzed and the development contexts are sorted out. On this basis, the paper further points out the future direction of the restoration technique based on deep learning of the super-resolution image.
