Keypoint matching and ORSA like algorithm

Hi all,

I am working on image alignment using SIFT algorithm; but this also applies to SURF.

Sometimes one needs to "refine" matching because of a few wrong match
in the list. The ORSA algorithm looks adapted (Moisan-Stival ORSA
(Optimized Random Sampling Algorithm) algorithm to filter out the false
matches using the epipolar geometry constraint) but it uses only the X
and Y coordinate of the keypoint and not the angle + orientation. Maybe
using those informations it would be easier to spot those outliers, no ?

Do you know an algorithm using those informations as well ?

Thanks,
