Detailed Description

template<typename TMask, typename TImage>
class itk::TernaryOperatorImageFilter< TMask, TImage >

Return the value of input 2 if input 1 is false, and that of input 3 otherwise.

Author: Davis Vigneault

This class is templated over the mask type and image type. Inputs two and three and the output image are all templated over the same type. If the value of Input1 evaluates to true, the value of Input2 is taken; otherwise, the value of Input3 is taken. This is equivalent to applying the ternary operator pixelwise across the three images:

Output = Input1 ? Input2 : Input3

As an example of where this filter could be useful, consider the case where you have the following images:

Foreground: An image containing an object of interest.
Background: An image containing a background for the object.
Mask: A boolean image where pixels corresponding to the object are true.

A new image with the foreground object placed on the background can be obtained as follows:

*
* typedef itk::TernaryOperatorImageFilter< MaskType, ImageType > TernaryType;
* TernaryType::Pointer ternaryFilter = TernaryType::New();
*
* ternaryFilter->SetInput1( maskImage );
* ternaryFilter->SetInput2( foregroundImage );
* ternaryFilter->SetInput3( backgroundImage );
*
* ImageType::Pointer objectOnBackground = ternaryFilter->GetOutput();
*
*
