I have found a reference of ippicv in the third party folder of OpenCV source code. Can you kindly comment whether a commercial license for ippicv is to be procured by a user who distributes OpenCV?
The ippEULA that was found in the OpenCV distribution lists different types of licenses from Intel. This is a source for confusion because the users of OpenCV cannot be sure if they have the right to distribute ippicv, if it is a part of the OpenCV distribution.
It would be really helpful if a clear answer is provided for this question, as there seems to be many persons who asked this question, but not got the right answer.
A subset of Intel® IPP (https://software.intel.com/en-us/ipp) is included by default to OpenCV builds on Intel platforms. This subset of IPP, called IPPICV, is free for all OpenCV users. IPP accelerates a number of kernels in OpenCV, mostly the image processing.
Intel has granted OpenCV Foundation and all users the right to use IPPICV libraries free of charge for both non-commercial and commercial use. Optimization with IPPICV is enabled by default on the supported platforms.
