Constructor & Destructor Documentation

FMatrixCompute7Point::FMatrixCompute7Point	(	bool	precondition = true,
		bool	rank2_truncate = true
	)

Initialize FMatrixCompute7Point object.

If precondition = false, points are not conditioned prior to computation. If rank2_truncate = false, the resulting solution is not forced to rank 2 using the vnl_svd<double>.

Member Function Documentation

bool FMatrixCompute7Point::compute	(	PairMatchSetCorner &	matches,
		vcl_vector< FMatrix * > &	F
	)

Compute a fundamental matrix for a set of point matches.

Compute a fundamental matrix for a set of 7 point matches.

Return false if the calculation fails or there are fewer than seven point matches in the list.

Return false if the calculation fails or there are fewer than eight point matches in the list.

bool FMatrixCompute7Point::compute	(	vcl_vector< HomgPoint2D > &	points1,
		vcl_vector< HomgPoint2D > &	points2,
		vcl_vector< FMatrix * > &	F
	)

Interface to above using arrays of HomgPoint2D.

Makes a PairMatchSetCorner, and then calls the compute method above.

vcl_vector< double > FMatrixCompute7Point::solve_cubic

(

vcl_vector< double >

v

)

[static, protected]

Solves a cubic and returns the real solutions.

Thus it returns a list of length 1 if there are 2 complex roots and 1 real, of length 2 if it is in fact a quadratic with 2 solutions, of length 3 if there are 3 real solutions a x^3 + b x^2 + c x + d = 0 Rewritten and documented by Peter Vanroose, 23 October 2001.

vcl_vector< double > FMatrixCompute7Point::solve_quadratic

(

vcl_vector< double >

v

)

[static, protected]

Gives solutions to 0x^3 + ax^2 + bx + c = 0.

Returns the set of real solutions, so if both are imaginary it returns an empty list, otherwise a list of length two. v is a 4-vector of which the first element is ignored.
