排序分组算法，虽然简单，值是基于灰度的算子，然后用平均值可使图片清晰；-a sort algorithm is simple, gray value is based on the operator, then the average will clear pictures;

利用GUI制作一简单图像处理系统，基本原理是将多幅加入高斯噪声的图象叠加求平均达到去除噪声的目的。-Using the GUI to make a simple image processing system, the basic principle is to add gaussian noise image superposition o on average to achieve the purpose of removing noise.
