Detailed Description

template<class TInputImage, class TCoordRep = float>
class itk::VectorLinearInterpolateNearestNeighborExtrapolateImageFunction< TInputImage, TCoordRep >

Linearly interpolate or NN extrapolate a vector image at specified positions.

VectorLinearInterpolateNearestNeighborExtrapolateImageFunction linearly interpolates (or NN extrapolates) a vector image intensity non-integer pixel position. This class is templated over the input image type and the coordinate representation type.

This class is designed to work as a VectorInterpolateImageFunction, hence the IsInsideBuffer(PointType p) is overridden to always answer true

This function works for N-dimensional images.

Warning
This function work only for Vector images. For scalar images use LinearInterpolateImageFunction.

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

Evaluate the function at a ContinuousIndex position

Returns the linearly interpolated image intensity at a specified point position. If the point does not lie within the image buffer a nearest neighbor interpolation is done.

Implements itk::VectorInterpolateImageFunction< TInputImage, TCoordRep >.

virtual OutputType itk::VectorLinearInterpolateNearestNeighborExtrapolateImageFunction< TInputImage, TCoordRep >::EvaluateAtIndex ( const IndexType index) const

Evaluate the function at an index position

Simply returns the image value at the specified index position. If the index does not lie within the image buffer a nearest neighbor interpolation is done.

Should check if an index is inside the image buffer, however we require that it answers true to use the extrapolation possibility.

Interpolate the image at an index position. Simply returns the image value at the specified index position. No bounds checking is done. The point is assume to lie within the image buffer.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.
