利用MATLAB中的GUI（图形用户界面），实现图像的灰度化，直方图，图像的错切变换，直方图均衡化，量化图像及图像的傅里叶频谱，是效果更加明显。-In MATLAB GUI (graphical user interface), to achieve graying, histogram, image conversion cut the wrong image, histogram equalization, quantized image and the image of the Fouri

实现二维图形的变换，平移、对称、旋转、错切等基本变换-The realization of two-dimensional graphics transformation, translation, symmetry, rotation, shear, such as the basic transform
