Noun

homography (countable and uncountable, plural homographies)

1. The state or quality of being spelt homographically; the state or quality of existing as homographs.
2. (geometry) An isomorphism between projective spaces 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.

   Synonyms: projectivity, projective transformation, projective collineation

   Hypernym: collineation

   Hyponyms: linear fractional transformation, Möbius transformation
