Detailed Description

RANSAC estimator to compute an affine homography from a set of 2D-2D correspondences The observations passed (via iterators) to the estimate method must allow:

TooN::Vector<2> a = first_point(*it); // default value is "(*it).first"
TooN::Vector<2> b = second_point(*it); // default value is "(*it).second"
double R = noise(*it); // default value is "1.0"

The resulting transformation will map from a -> b.
