利用MATLAB GUI设计实现图像处理的图形用户界面，利用MATLAB图像处理工具箱

实现以下的图像处理功能。

1、　　采用matlab Guide设计图像界面与按钮界面。

2、　　连接摄像头，编写MATLAB初始化程序。

3、　　用摄像头采集一幅图像，并能实现保存（使用控件按钮保存）。

4、　　设计按钮实现对图像进行任意的亮度和对比度变化调节，显示和对比度变化前

后的图像

5、设计按钮实现用户能够用鼠标选取图像感兴趣区域，显示和保存该选择区域。

-Image processing using MATLAB GUI design graphical user interface, using the MATLAB image processing toolbox

Implement the following image processing functions.

1, Guide design based on matlab image with the button interface.

2, connect camera, write MATLAB initialization.

3, use camera to collect an image, which can be saved using the control button to save).

4, design button implementation for any changes in brightness and contrast adjustment, display and contrast changes before

After the image of the

5, design interest to be able to use the mouse to　the image button to achieve the user area, display and save the selected area.
