image processing - Difference between HomographyBasedEstimator and findHomography OpenCV -

-

i trying write program stitches images using surf detector , know difference between 2 homography estimator. understand findhomography uses ransac, homographybasedestimator using ransac too?

if isn't, point me paper homographybasedestimator used?

thanks in advance

the main difference between both functions findhomography, name says, used find homography, , homographybasesestimator uses existing homographies calculate rotation of cameras.

i mean, homographybasesestimator doesn't find homographies, use them computation of camera motion , other camera parameters such focal lengths , optical centers.

i hope can you.
