Homography
In projective geometry, a homography is an isomorphism of projective spaces, induced by an isomorphism of the vector spaces from which the projective spaces derive. It is a bijection that maps lines to lines, and thus a collineation. In general, some collineations are not homographies, but the fundamental theorem of projective geometry asserts that is not so in the case of real projective spaces of dimension at least two. Synonyms include projectivity, projective transformation, and projective collineation.

\ho*mog"ra*phy\ (?), n.
1. that method of spelling in which every sound is represented by a single character, which indicates that sound and no other.
2. (geom.) a relation between two figures, such that to any point of the one corresponds one and but one point in the other, and vise versa. thus, a tangent line rolling on a circle cuts two fixed tangents of the circle in two sets of points that are homographic.
