四、课程设计内容：本图像处理系统是基于MATLAB的GUI平台，仿照Photoshop、Neo等图像处理软件制作而成的，是一个简易的图片处理系统。

其中以图像加解密、图像美容、图像锐化等方法为本系统特色。

图像加解密：采用密钥与图像分离的方法对图像加密。

图像美容：采用多个函数分别对图像色彩、明暗、对比度、饱和度等多个参数进行调节，适用于大多数图片。

图象锐化：采用多次迭代的方法实现。

五、系统的软硬件环境：1.系统的软件环境操作系统：Windows 95\Windows 98\Windows 2000\Windows XP 或更高。

安装软件：MA TLAB6p52.系统的硬件环境（1）CPU的最低配置为80586/133MHz，推荐使用586以上的处理器。

（2）容量至少为16MB的RAM，推荐为32MB以上内存。

（3）使用VGA或VGA以上的显示卡及高分辨率的显示器。

（4）除了配置鼠标、键盘和CD-ROM外，如果需要接入Internet，还需配置Modem或网卡。

这为我以后的人生之路是否会走好打下了坚定的基础，以致于在以后的求取过程中少走些弯路，也不致于因一些小挫折而迷失了自己的方向。

课程设计教会我很多的东西，平时不注意的细节，在课程设计中都有所注意，平时没看懂的东西，基本上都能看懂了。

同学们之间的友谊也更进了一步。

特别是在做课程设计时，同学们表现出来的那股热情，那种勤奋，是从来没有过的，课程设计后，我们发现我们对这门课程探索欲愈来愈深，因为它使我们产生了许多的疑惑，虽然书上讲了许多理论知识，但是对于这门学科光有理论而没有实践是不行的。

总之，对于这次课程设计的学习，命名我受益匪浅。

我发现对于这门学科人愈喜爱了，对知识的渴求愈来愈强烈。
