Hello,
I have a question regarding "Haar Feature-based Cascade Classifier for Object Detection". Is it possible to use CascadeClassifier class in closed code and commercial project (e.g. CascadeClassifier::detectMultiScale function), including haarcascade_*.xml files distributed with OpenCV? Is it free for commercial use? I mean, no patent restrictions, etc.? This is not clearly explained anywhere. Please, give some feedback on that issue.
Thanks in advance!
