I see from the docs that OpenCV 3.4.2 uses Intel's OpenVino inference engine as the DNN backend by default (if you include it in compilation).
However, when I went to go obtain OpenVino, I found I was drowning in dozens of legal documents trying to figure out exactly how the inference engine and its various components (required redist dependencies and such) are licensed. I even saw scary language about Intel reserving various patent rights.
My question is, where is the developer discussion around including this apparently patent (or at least license) mine-field software? I ask because there must have been some discussion about the licensing nightmare before integrating it into OpenCV, so maybe if I were to see that discussion I might simply discover that I've misunderstood something.
