AdjustHomographyMatrix 
The scale and sign of a homography matrix is ambiguous.

HomographyDirectLinearTransform 
Using linear algebra it computes a planar homography matrix using 2D points, 3D points, or conics.

HomographyInducedStereo2Line 
Computes the homography induced by a plane from 2 line correspondences.

HomographyInducedStereo3Pts 
Computes the homography induced by a plane from 3 point correspondences.

HomographyInducedStereoLinePt 
Computes the homography induced by a plane from correspondences of a line and a point.

HomographyResidualSampson 
Computes the Sampson distance residual for a set of observations given a homography matrix.

HomographyResidualTransfer 
Computes the difference between the point projected by the homography and its observed location.

HomographyTotalLeastSquares 
Direct method for computing homography that is more computationally efficient and stable than DLT.
