homography

Definitions

1. The state or quality of being written in the same way, especially when spelled with the same letters (as with a pair of homonyms), or also as represented with similar or identical glyphs (as with homoglyphs); the state or quality of existing as homographs.
   countable, uncountable
2. An isomorphism between projective spaces that maps straight lines to straight lines.
   countable, uncountable

Examples

“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.”
