Detailed Description

template<class TImage, class TOutputPixelType>
class itk::NthElementImageAdaptor< TImage, TOutputPixelType >

Presents an image as being composed of the N-th element of its pixels.

It assumes that the pixels are of container type and have in their API an operator[]( unsigned int ) defined.

Additional casting is performed according to the input and output image types following C++ default casting rules.

Wiki Examples:

All Examples

Extract a component/channel of an itkImage with pixels with multiple components

Process the nth component/element/channel of a vector image

Examples:: itkVectorImageTest.cxx.
