Abstract: Image super-resolution reconstruction technology is to deal with the input low resolution image, so as to reconstruct the high resolution image, which has become a hotspot in the field of image processing. In this paper, the research progress of image super-resolution reconstruction is reviewed. Firstly, the basic principle of image super-resolution reconstruction is described. Secondly, the algorithms of IBP and POCS in image super-resolution reconstruction based on reconstruction, the algorithms of sparse representation and deep neural network in super-resolution reconstruction based on learning and some related algorithms are reviewed. Finally, the prospect of image super-resolution reconstruction is proposed.
