homest Description

A C/C++ Library for Robust, Non-linear Homography Estimation homest is a free and open source C/C++ library for homography estimation.A homography (sometimes also called a collineation) is a general plane to plane projective transformation whose estimation from matched image features is often necessary in several vision tasks. A homography has eight degrees of freedom and is represented by a non-singular homogeneous 3x3 matrix. homest implements a technique for non-linear, robust homography estimation from matched image point features. This technique computes a homography estimate that minimizes an appropriate cost function defined on matching points (currently either non-symmetric transfer error, symmetric transfer error, Sampson error or reprojection error) and includes robust regress
