% SUPERRESOLUTION - 超分辨率成像的图形用户界面
% This program allows a user to perform registration of a set of low 
% resolution input images and reconstruct a high resolution image from them.
% 这个程序可以使用户从一系列低分辨率的输入图像来重建一个高分辨率的图像
% Multiple image registration and reconstruction methods have been
% implemented. As input, the user can either select existing images, or 
% generate a set of simulated low resolution images from a high resolution 
% image. 
% 多种图像配准和图像重建的方法被应用到。输入方面用户可以选择已经存在的低分辨率图像或者利用
% 高分辨率图像生成一系列模拟低分辨率图像
