惯用图像处理算法（三）

发布时间： 2012-12-23 11:28:15 作者： rapoo

常用图像处理算法（三）

算法依赖的环境，动态库包括libtiff3.dll、jpeg62.dll、convert.dll、imgConv.dll。其中前两个从网上下载tiff、jpeg类后可以自动生成。后面两个类是Che同学给的，在此感谢他，我把这些类放到图片里面，如果能够上传就好了。CSDN做的真不够人性，不能添加附件。先试试。貌似没有成功。放到资源里面了大家可以免费下载。

我在MFC的CView类中实现函数的功能调用。

1）头文件

// ImgProcessView.h : CImgProcessView 类的接口
