I am doing some research in Local Feature representation, so SIFT, SURF and such.

Now, has anybody here ever tried BRIEF and ORB? If so, can you discuss what are some of the pro and con with respective to SIFT?

here is one comparison I have found helpful. Essentially BRIEF and ORB are much faster. There is not a good comparison of scale invariance there but personally I have found SURF/SIFT to be more scale invariant than BRIEF and ORB. I recommend if you are going to use these for a specific use case you try both to see which meets your needs best.
