template<class T >

const FixedVector<3,T> cmtk::AnatomicalOrientation::PermutationMatrix::GetPermutedArray ( const FixedVector< 3, T > & source ) const [inline]

Takes the dimensions of a volume (e.g.

a grid, a voxel) and returns the dimensions of that volume after the reorientation described by this permutation matrix

Parameters:

source Original array

Returns:: target A three-element array to contain the permuted results.

void cmtk::AnatomicalOrientation::PermutationMatrix::GetReorientedIndex	(	const int *	origPoint,
		int *	newPoint
	)		const `[inline]`

Get new point index from old point index.

Parameters:

origPoint	The input pixel index in the original image grid.
newPoint	The output pixel index in the reoriented image grid.

size_t cmtk::AnatomicalOrientation::PermutationMatrix::NewOffsetFromPoint ( const int * origPoint ) const [inline]

Applies the permutation described by this matrix to a pixel index.

Parameters:

origPoint The input pixel index.

Returns:: The offset of the corresponding pixel in the reoriented volume.

Member Data Documentation

FixedVector<3,int> cmtk::AnatomicalOrientation::PermutationMatrix::m_Axes [private]

Input-to-output axis index assignments.

m_Axes[i] contains the index (0, 1, or 2) of the axis of the input orientation which gets moved to as the i'th axis of the output orientation. (where i is 0, 1, or 2, corresponding to X, Y, and Z, respectively)

Definition at line 144 of file cmtkAnatomicalOrientation.h.

FixedVector<3,int> cmtk::AnatomicalOrientation::PermutationMatrix::m_Multipliers [private]

Multiplies (flip direction) table.

m_Multipliers[i] contains -1 if the axis at m_Axes[i] is to be reversed from its direction prior to re-orientation, and 1 otherwise

Definition at line 151 of file cmtkAnatomicalOrientation.h.

FixedVector<3,int> cmtk::AnatomicalOrientation::PermutationMatrix::m_NewDims [private]

Dimension of the reoriented image in the direction of m_Axes[i].

Definition at line 156 of file cmtkAnatomicalOrientation.h.

FixedVector<3,int> cmtk::AnatomicalOrientation::PermutationMatrix::m_Offsets [private]

m_Offsets[i] contains 0 if m_Multipliers[i] == 1, and (m_NewDims[i] - 1) if m_Multipliers[i] == -1.

(Since in the latter case, we will be writing from the highest-valued pixel in direction i and iterating backwards.)
