Detailed Description

template<class TInputImage, class TCoordRep = double>
class itk::LinearInterpolateImageFunction< TInputImage, TCoordRep >

Linearly interpolate an image at specified positions.

LinearInterpolateImageFunction linearly interpolates image intensity at a non-integer pixel position. This class is templated over the input image type and the coordinate representation type (e.g. float or double).

This function works for N-dimensional images.

This function works for images with scalar and vector pixel types, and for images of type VectorImage.

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. 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.
