14 Nov 2012 2D - 2D Projective Homography (3x3) Estimation This function estimates 2D-2D projective homography between two images. Author: SasiKanth

Can anyone please tell me if there any difference between the homest2d of this code and the Normalized NDLT (Hartley and Zisserman: Multiple View Geometry in Computer vision)?

Hi Mr SasiKanth
I am needed to find estimation for the homography 2D that can relate a big number of points (100, 250...)
And i found this code is very interesting, especially the function homest2D

But if you may I have some question about homest2D:
1) Why you are using approximately the same approach of Fundamental Matrix? and what this can help?
2) if we have 2 sets of points, is homest2D enough to calculate the homography?
3) did you do any experimentation with homest2D? or any comparison with other algorithm, like Normalized DLT (Hartley and Zisserman: Multiple View Geometry in Computer vision)?
Thank you in advance for any help, and if you may have any document that explain each step of the algorithm, i will be very thankful
Thank you again
