Overview of Research on Image Super-Resolution Reconstruction

Image super-resolution reconstruction refers to reconstructing a high-resolution image from a low-resolution image through a corresponding method, that is, to generate a clearer image. Throughout the development of this technology, we can see the results of previous efforts, such as image super-resolution reconstruction based on interpolation, image super-resolution reconstruction based on reconstruction, super-resolution reconstruction based on learning, and image super-resolution reconstruction technology based on deep learning. Nowadays, the idea of deep learning is very popular. It is an important branch of machine learning and is widely concerned and favored by researchers. Combining deep learning ideas into the research of image super-resolution reconstruction can achieve very satisfying effects. In this paper, we mainly describe various algorithms of image super-resolution reconstruction based on deep learning, compare their advantages and disadvantages, and discuss their future development directions.
