Detailed Description

template<class TCoordRep = double, unsigned int VIndexDimension = 2>
class itk::ContinuousIndex< TCoordRep, VIndexDimension >

A templated class holding a point in n-Dimensional image space.

ContinuousIndex is a templated class that holds a set of coordinates (components). The template parameter TCoordRep can be any data type that behaves like a primitive (or atomic) data type (int, short, float, complex). The VIndexDimension defines the number of components in the continous index array.

void itk::Point< TCoordRep , NPointDimension >::SetToBarycentricCombination ( const Self *  P,
const double *  weights,
unsigned int  N 
) [inherited]

Set the current point to a barycentric combination of an array of N points An array of (N-1) values is expected to weight the contribution of the first (N-1) points, the weight of the Nth point is computed to ensure that the N weights sum 1.

This method computes:

\[ \overrightarrow{P}= \sum_{i=1}^{N-1} w_i * \overrightarrow{P}_i + \left(1- \sum_{i=1}^{N-1} w_i\right) * \overrightarrow{P}_N \]

void itk::Point< TCoordRep , NPointDimension >::SetToBarycentricCombination ( const Self &  A,
const Self &  B,
const Self &  C,
double  weightA,
double  weightB 
) [inherited]

Set the current point to a barycentric combination of three points Two values are expected to weight the contribution of the first two points, the weight of for the third point is computed to ensure that the three weights sum 1.

This method computes:

\[ \overrightarrow{P}= w_1 * \overrightarrow{P}_1 + w_2 * \overrightarrow{P}_2 + (1-w_1-w_2 ) * \overrightarrow{P}_3 \]

If the two weight are $ \in [0,1] $ , The resulting point will alway be placed inside the triangle formed by the three points given as arguments.

void itk::Point< TCoordRep , NPointDimension >::SetToBarycentricCombination ( const Self &  A,
const Self &  B,
double  alpha 
) [inherited]

Set the current point to a barycentric combination of the two points given as arguments.

Parameters:
A First point
B Second point
alpha Weight for the first point

The first point is multiplied by $ \alpha $, the second is multiplied by * $ (1-\alpha) $, and the sum is stored in the Point on which the method is invoked.

\[ \overrightarrow{P}=\alpha * \overrightarrow{A}+ (1-\alpha)*\overrightarrow{B} \]

If the value of $ \alpha \in [0,1] $, the resulting point will be placed in the line segment $ \overline{AB} $ joining $ \overrightarrow{A} $ and $ \overrightarrow{A} $

If the value of $ \alpha < 0 $ the resulting point will be placed outside the line segment $ \overline{AB} $ on the side of $ \overrightarrow{A} $.

If the value of $ \alpha > 1 $ the resulting point will be placed outside the line segment $ \overline{AB} $ on the side of $ \overrightarrow{B} $.

SetToMedian
void itk::Point< TCoordRep , NPointDimension >::SetToMidPoint ( const Self &  ,

) [inherited]

Set to median point between the two points given as arguments

This method computes:

\[ \overrightarrow{P}=\frac{(\overrightarrow{A}+\overrightarrow{B})}{2} \]

using the two Points given as arguments, and store the result in the Point on which the method is invoked.
