2013-06-12 13:41:15 -0600	asked a question	Get a precision-recall graph for a recognition system Hi all, i recently developed a sift-based recognition system and i'd like to get some measure of performance for it. I read about a "threshold" parameter which should be chosen to get precision-recall curves. I can't understand what this means. What exactly should i increase/decresce to plot the curve? Thank you.

2012-12-27 09:40:02 -0600	asked a question	Setting up a new project in Qt-creator using OpenCV and PCL Hi all, i successfully installed OpenCV and PCL using respectively the script at https://github.com/DmitrySandalov/Install-OpenCV/blob/master/Ubuntu/2.4/opencv2_4_3.sh and the official documentation at http://pointclouds.org/downloads/linux.html. My question is : how can i set up a new project for using both OpenCV and PCL with Qt Creator? I also noticed that Qt offers some options for using cmake files but i'm really new to the all thing, can someone please explain it to me?
