Member Function Documentation

template<class I>

virtual bool cvr::matrixTransform< I >::matrixTransform::helper4x3::analyzeMatrix

(

)

[virtual]

Analyze the matrix in the parameters and compute its inverse.

If the matrix is not invertible, then return false.

Reimplemented from cvr::matrixTransform< I >::matrixTransform::helper4x4.

template<class I>

virtual bool cvr::matrixTransform< I >::matrixTransform::helper4x3::evalDims	(	const ipoint &	orig,
		ipoint &	res,
		fpoint &	offset
	)			const [virtual]

After the matrix has been analyzed, this method can be used to compute the dimensions of the resulting image and the offset.

Reimplemented from cvr::matrixTransform< I >::matrixTransform::helper4x4.

template<class I>

bool cvr::matrixTransform< I >::matrixTransform::helper4x3::trans	(	const fmatrix &	m,
		const ipoint &	p,
		fpoint &	res
	)			const

Get the transformation of the given point (x,y) extending it to homogeneous coordinates (x,y,0,1), and normalizing the result.

Reimplemented from cvr::matrixTransform< I >::matrixTransform::helper4x4.
