HomoGrTb - Homography Estimation Toolbox


This package contains a Matlab toolbox for 2D point correspondence based homography estimation for various homographies (isometry, similarity, affinity, projectivity).

Version 0.1.0 is the first public version which has been tested and therefore should be at least somehow reliable.
