数字图像处理，完成Matlab GUI程序或C/C++程序，有两个显示区域，实现功能：

1）读入灰度或彩色图像，可放大缩小显示；

2）完成图像对比度的简单、分段线性变换及非线性变换，并与原图像对比显示；-Digital image processing, Matlab GUI to complete the program or C/C++ program, there are two display areas, to achieve functional: 1) read in grayscale or color images, you can zoom the display　2) complete the image contrast is simple, piecewise linear transformation and non-linear transformation, and comparison with the original image display
