本文详细介绍了如何从GitHub下载并编译OpenCV，以及在项目中正确配置OpenCV库的过程。通过对比自写算法与OpenCV的性能，发现OpenCV的ipp加速和OpenCL支持显著提升效率。文章还分享了配置过程中遇到的问题及解决方案，如动态库的拷贝、头文件和静态库的路径设置，以及在不同编译模式下如何引用库。

自己用线程写出的膨胀算法竟然比opencv慢，为此查看opencv源码

安装

直接搜opencv，官网

到github下载版本多但慢===很慢对应网站下载编译

https://github.com/opencv/opencv/releases

build /install 中的东西有用

配置

头文件包含目录install 下的include
添加附加静态库库目录lib
把动态库拷贝到输出目录下面
加上下面到话不需要配置输入库名
