Research on Registration Algorithm in Super-Resolution Reconstruction of Video Image

Abstract

In super-resolution reconstruction, there exists the defect that common template matching costs much memory and time. In this paper, the template matching algorithm is optimized. Firstly, a mathematical model of super-resolution is established. Then, the importance of image registration is discussed in super-resolution reconstruction of video image. Subsequently, the method of template matching for registration is put forward and the specific steps of algorithm are described. At the same time, the defects of template matching algorithm are analyzed. Finally, the algorithm of template matching has been improved to optimize the registration time. The experimental results show that the time used by this algorithm is half of the time used by the original template matching algorithm.
