OpenCV & IPP

 

下载IPP：https://software.intel.com/en-us/performance-libraries

 

包含如下libraries：

 

 

 须要注册而后进入以下页面，选择IPP for windows下载：

安装完毕后，

• 配置环境变量：

在环境变量中的Path上添加下面路径（注意你的安装路径，32位电脑添加相应32位路径）：C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2019.5.281\windows\redist\intel64_win\ipp

环境变量配置完成以后注意重启生效！

• 配置IDE：

新建一个控制台程序，选择项目属性->VC++目录，在可执行文件，包含目录，库目录中分别添加以下路径（注意安装路径）：

1. 可执行文件目录：C:\Program Files(x86)\IntelSWTools\compilers_and_libraries_2019.5.281\windows\redist\intel64_win\ipp
2. 包含目录：C:\Program Files(x86) \IntelSWTools\compilers_and_libraries_2019.5.281\windows\ipp\include
3. 库目录：C:\Program Files(x86)\IntelSWTools\compilers_and_libraries_2019.5.281\windows\ipp\lib\intel64_win
