# feature detectors and descriptors comparison

There are several kinds of detectors and descriptors, like SIFT, SURF, FAST. I wonder are they all eligible for real-time applications? Which is the best or better?

And furthermore, is Harris-Laplacian dectector still useful when we already have the above three? Is it better than them?

• @loganecolss its depend on your use , you can read about it here : http://www-scf.usc.edu/~boqinggo/Feature.htm and as i stated above i didn't use it , thats why i didn't describe it in my answer – ARG Aug 26 '13 at 18:22
