What is Integrated Performance Primitives (IPP)?
Intel® Integrated Performance Primitives (Intel® IPP) is an extensive library of multicore-ready, highly optimized software functions for multimedia, data processing, and communications applications. Intel IPP offers thousands of optimized functions covering frequently used fundamental algorithms.
There is a free non-commercial version of IPP for Linux available on the IPP website. Download and install this package. After installation configure OpenCV to enable IPP (USE_IPP=ON) and set the IPP path variable (IPP_PATH) to the correct location.
