Detailed Description

template<typename TImage>
class itk::CheckerBoardImageFilter< TImage >

Combines two images in a checkerboard pattern.

CheckerBoardImageFilter takes two input images that must have the same dimension, size, origin and spacing and produces an output image of the same size by combinining the pixels from the two input images in a checkerboard pattern. This filter is commonly used for visually comparing two images, in particular for evaluating the results of an image registration process.

This filter is implemented as a multithreaded filter. It provides a ThreadedGenerateData() method for its implementation.

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.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

overrideprotectedvirtual

CheckerBoardImageFilter can be implemented as a multithreaded filter. Therefore, this implementation provides a ThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling ThreadedGenerateData(). ThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread"
