List of all members.

Public Member Functions
	Homography ()
void	project (float x, float y, float &correctedX, float &correctedY)
	Projects (x,y) to the corrected values (correctedX, correctedY) based off the homography matrix.
void	invertProjection (float correctedX, float correctedY, float &x, float &y)
	Inverts (correctedX, correctedY) to the original values (x,y) from the homography matrix inverse.
fmat::Matrix< 3, 3 > &	getMatrix ()
	Returns the homography so far, recomputes H if out of date.
fmat::Matrix< 3, 3 > &	getMatrixInverse ()
void	addCorrespondence (double actualx, double actualy, double imagex, double imagey)
	Adds a correspondence to the list. actualx and actualy are the corrected values, imagex and imagey are the perceived values.
Private Attributes
fmat::Matrix< 9, 9 >	A
	The matrix that holds the correspondences.
fmat::Matrix< 3, 3 >	h
	The matrix that holds the computed homography.
fmat::Matrix< 3, 3 >	hInv
	The matrix that holds the inverse of the computed homography.
bool	isDirty
	Whether the homography is out of date with how many correspondences have been added.
