Detailed Description

Static class for the estimation of homographies.

Provides functions to estimate the homography.

from 4 point correspondences or
from n point correspondences.

From 4 point correspondences: Use one of the estimate() functions:
homography::estimate(H, u1, v1, up1, vp1, u2, v2, up2, vp2, ...)

or
CvMat * H = homography::estimate(H, u1, v1, up1, vp1, u2, v2, up2, vp2, ...)

Estimates H using a linear method.

From n correspondences if H0 != NULL, it is used to initialize H. H0 can be an affinity matrix. c is the parameter of the Tukey robust estimator.
