Intel IPP is supposed to speed up certain operations in OpenCV. To try that I compiled OpenCV with support for Intel IPP using these steps:
- Download and install Intel IPP as explained here. Make sure that the
IPPROOTenvironment variable is set.
In the CMake compilation string, add the following option:
You should be able to compile OpenCV with IPP support now.
Note: I had tried to compile OpenCV with Intel IPP 8.0. But, I got a few undefined reference errors with those, which I could not resolve.
Tried with: OpenCV 2.4, Intel IPP 7.1 and Ubuntu 12.04 LTS
