MatchPoint, as it is now officially called, was a Google Summer of Code 2007 project. Zoran Mesec, mentored by Dr. Herbert Bay, worked on a feature detector to replace the patented SIFT algorithm. He succeeded, but at the end of the summer his code had still performance issues. He kept improving it on his little spare time from university. He committed some code just before his exams, and now he committed again a version that he asked the community to test.
Building it in Linux was easy, and it passed the test as drop in replacement for generatekeys in autopano quite nicely, and it is actually slightly faster than generatekeys.
