Enable Intel® IPP on OpenCV* (Windows* and Ubuntu*)

Introduction

This article explains how to enable Intel® Integrated Performance Primitives (Intel® IPP) with OpenCV* for improved performance benefits and efficiency of hardware resources.

Setup for Windows* Systems

To configure OpenCV and enable Intel IPP, do the following:
 

1. Download OpenCV 4.x or above and CMake.
   This example uses OpenCV 4.x and CMake 3.30.0-rc4.
2. Extract OpenCV to your chosen file location.
3. Install CMake, and then run the CMake GUI.
4. Add the location of OpenCV as the source location, and then choose a location where you want your build to be created.
5. Choose your generator. For example, 'Visual Studio 17 2022 Win64'
6. Enable Intel IPP using either of the following options:
   • Use the free 'ICV', which is a special Intel IPP build for OpenCV provided in Intel IPP.
   • Use Intel IPP from any Intel software tool suite (Intel® oneAPI Base Toolkit or as a stand-alone component).
7. To use ICV, turn on WITH_IPP. The Intel IPP ICV package downloads automatically, and the CMake configuration catches it.
   
   
   
8. To enable Intel IPP from an Intel software toolkit, in addition to setting WITH_IPP, manually add an entry for Intel IPP.
   • Select Add Entry.
   • In the Name field, enter IPPROOT.
   • In the Type field, choose PATH.
   • In the Value field, enter the file location where you downloaded Intel IPP.
9. The following screenshot shows an example configuration with Intel® oneAPI Base Toolkit 2024.2.
   
   
   
   
   
10. To build OpenCV with your generator, select Generate.

Setup for Linux* and Ubuntu* Systems

To configure OpenCV and enable Intel IPP, do the following:
 

1. Download OpenCV 4.x or above. This example uses OpenCV 4.x.
2. Extract OpenCV to your chosen file location.
3. Open a terminal and go to where you extracted OpenCV.
4. Enable Intel IPP using either of the following options:
   • Use the free 'ICV', which is a special Intel IPP build for OpenCV provided in Intel IPP.
   • Use Intel IPP from any Intel software tool suite (Intel® oneAPI Base Toolkit or as a stand-alone component).
5. For ICV, type mkdir build && cd build && cmake .. -DWITH_IPP=ON. Following is an example of the configuration for ICV.
6. For Intel IPP from an Intel software toolkit, type mkdir build && cd build && cmake .. -DWITH_IPP=ON -DIPPROOT=<Your IPP Location>
7. The following example shows the configuration result.
8. If the configuration went without a problem, type make -j4
9. When the building is complete, to install the library, type make install.
