    (uncountable)
    1. The state or quality of being spelt homographically; the state or quality of existing as homographs.
    2. (geometry) An invertible transformation from a projective space to itself that maps straight lines to straight lines.A homography on a real projective plane can be specified by a mapping from one set of four non-collinear points to another set of four non-collinear points. Given such a specification, then the 3-by-3 homography matrix may be computed by means of the DLT (Direct Linear Transformation) algorithm.
