template<typename TInputImage1, typename TInputImage2>
class itk::SimilarityIndexImageFilter< TInputImage1, TInputImage2 >
Measures the similarity between the set of non-zero pixels of two images.
SimilarityIndexImageFilter measures the similarity between the set non-zero pixels of two images using the following formula:
![\[ S = \frac{2 | A \cap B |}{|A| + |B|} \]](form_190.png)
where 
and 
are respectively the set of non-zero pixels in the first and second input images. Operator 
represents the size of a set and 
represents the intersection of two sets.
The measure is derived from a reliability measure known as the kappa statistic. 
is sensitive to both differences in size and in location and have been in the literature for comparing two segmentation masks. For more information see: "Morphometric Analysis of White Matter Lesions in MR Images: Method and
Validation", A. P. Zijdenbos, B. M. Dawant, R. A. Margolin and A. C. Palmer, IEEE Trans. on Medical Imaging, 13(4) pp 716-724,1994
This filter requires the largest possible region of the first image and the same corresponding region in the second image. It behaves as filter with two input and one output. Thus it can be inserted in a pipeline with other filters. The filter passes the first input through unmodified.
This filter is templated over the two input image type. It assume both image have the same number of dimensions.

template<typename TInputImage1 , typename TInputImage2 >
What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierarchy. Up till now, the base assumption has been that the largest possible region will be requested of the input.
This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types.
