The goal of the lab is to estimate homography transformation between two images in the presence of outliers.
Use http://cmp.felk.cvut.cz/~wbsdemo/demo/ to obtain tentative correspondences (containing both, inliers and outliesr).
Sample sets of 4 point-to-point correspondences at random, estimate 2D homography and evaluate the support set.
See Matlab function randperm .
Use all inliers to re-estimate the final model.
