Homography

Saw this word from this paper: https://arxiv.org/pdf/2005.04078v1.pdf

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 the field of computer vision, any two images of the same planar surface in space are related by a homography.”
