The aim of super resolution is to get high resolution (HR) images/videos from low-resolution (LR) images/videos. The obtained HR images/videos are expected to be clear and have less artifacts. Projection Onto Convex Sets (POCS) in the space domain is a super resolution method. It results in edge oscillation and produces many artifacts. This paper introduces a POCS method in both the space and the frequency domain. Firstly, a frequency domain POCS method is proposed. Then it is combined with thedoi:10.4304/jcp.9.8.1959-1966 fatcat:zum6f2cxezd7hhzqtkdc5zh7ky
