The ability I like best about this software package was its ease in creating my own patterns from scratch with many different shapes as well! You can do so much more than just create circles or squares which are usually what most people think first when they hear "pattern".
It's also very customizable if you're looking at other options out there such has SURF Detector (which will be integrated soon). If your interested into computer vision/image processing then definitely give PatterRecognitonToolBox Software Package by Gert van Lamsweerde & Vincent Duchaux A try!! There isn't anything really bad i dislike but maybe some features could have been better explained during setup process because we had no idea how everything would work together until after downloading all our files etc.. We were able get around any problems easily using help feature though once installed properly!
