Abstract

Super-resolution (SR) processing reconstructs a high-resolution image from a set of low-resolution images for same scene. Spatial domain approaches in the super resolution algorithm were widely used. In this paper, we purposed an algorithm that converts the spatial domain into the frequency domain through the 2-dimension DFT for four low-resolution images. Utilizing the horizontal and vertical DFT (Discrete Fourier Transform) phase spectrum carry the horizontal and vertical direction feature information in frequency domain, we can make a high resolution image presented more visible details. We verify accuracy and efficiency from experimental results.
