Survey of super-resolution algorithms

With the development of high-resolution mobile devices and ultra-high-definition televisions, applying super-resolution up-sampling to the existing low-resolution video has become a hot research topic recently. In this paper, according to the different way of input and output, the existing super-resolution reconstruction algorithms are divided into three categories, i.e., multiple-image super-resolution reconstruction, single-image super-resolution reconstruction, and video super-resolution reconstruction. The development and common usage of each category are reviewed, and the characteristics of different algorithms are compared. In the following, the impact of multi-image super-resolution reconstruction and single-image super-resolution reconstruction on video super-resolution reconstruction is discussed. Finally, the development prospect of super-resolution reconstruction algorithm is analyzed.
