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.
