Detailed Description

This class is used for multi-rigid transformations, the first, index 0, is for MR the rest (n-1) are for echo images, respectively. To access the rigid transformation, use GetMRRigidTransform(void), GetEchoRigidTransform(index_of_echo) to get the transformation matrix from Echo to MR use GetMatrixFromEcho2MR(index_of_echo) CAN NOT be used as A transformation type for transforming AN image, ad hoc class To use as storage for transformation, SetDimension,SetNoOfRigidTransform first.

bool zxhTransformMultiRigid::GetMatrixFromEcho2MR	(	int	index,
		zxhTransformMatrix *	pMatrix
	)		[virtual]

return the matrix for echo images, index=1...m_nNoOfRigidTransform-1 which is T(echo,index)*INV(T(MR)) if index==0, error

float zxhTransformMultiRigid::GetMaxLocalMagnitudeAndNormalisation

(

bool

bNormalisationByLocalMagnitude

[virtual]

------ transformation ----------- ///// for optimisation step length normalisation

Reimplemented from zxhTransformBase.

virtual int zxhTransformMultiRigid::GetNoParameters

(

)

[inline, virtual]

Get partial differential of transformation [Y1 Y2 Y3]=T(x), with respect to the transformation parameter Ti with index return whether success, results (e.g. 3D, [d(Y1)/d(Ti) d(Y2)/d(Ti) d(Y3)/d(Ti)]) returned in g[4]

Implements zxhTransformBase.

virtual std::string zxhTransformMultiRigid::GetTransformType

(

)

[inline, virtual]

zxhTransformBase needed return image type string in upper case, currently have

Reimplemented from zxhTransformBase.

bool zxhTransformMultiRigid::SetParameterValue	(	int	index,
		float	f
	)		[virtual]

set transformation parameter value, if the transformation model need pre-computation from parameters for efficiency such as affine, then re-implement this function to call the pre-computation method after set the value

Implements zxhTransformBase.
