#include <itkMatchCardinalityImageToImageMetric.h>
Computes similarity between two objects to be registered.
This Class is templated over the type of the fixed and moving images to be compared.
This metric computes cardinality of the set of pixels that match exactly between the moving and fixed images. The spatial correspondance between both images is established through a Transform. Pixel values are taken from the Moving image. Their positions are mapped to the Fixed image and result in general in non-grid position on it. Values at these non-grid position of the Fixed image are interpolated using a user-selected Interpolator.
This metric is designed for matching label maps. All pixel mismatches are considered equal whether they are between label 1 and label 2 or between label 1 and label 500. In other words, the magnitude of an individual label mismatch is not relevant, or the occurrence of a label mismatch is important.
Given the nature of label maps, a nearest neighbor interpolator is the preferred interpolator.
The metric measure can measure the number of pixel matches (pixels with exactly the same label) or pixel mismatches (pixels with different labels). The returned metric value is the number of pixel matches (or mismatches) normalized by the number of pixels considered. The number of pixel considered is a function of the number of pixels in the overlap of the fixed and moving image buffers conditional on any assigned masks.

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.

Get the derivatives of the match measure.

Set/Get whether this metric measures pixel matches or pixel mismatches. Note the GetValue() returns the number of matches (or mismatches) normalized by the number of pixels considered. In other words, the metric measures the percentage of pixel matches or mismatches. The default is to measure matches (MeasureMatchesOn).

Non-const version of GetValue(). This is a hack around various const issues with trying to spawn threads from the const version of GetValue().
MeasureType itk::MatchCardinalityImageToImageMetric< TFixedImage, TMovingImage >::GetValue | ( | const TransformParametersType & | parameters | ) | const |
Get the value of the metric at a particular parameter setting. The metric value is the number of pixel matches (or mis-matches, see SetMeasureMatches()) normalized by the number of pixels under consideration (within the buffer and if specified within a mask). In other words, the metric measure the percentage of pixel matches or mismatches.

Split the FixedImageRegion into "num" pieces, returning region "i" as "splitRegion". This method is called "num" times. The regions must not overlap. The method returns the number of pieces that the routine is capable of splitting the FixedImageRegion, i.e. return value is less than or equal to "num".

Thread worker routine to calculate the contribution of the a subregion to the overall metric. Can only be called from GetValue().

Static function used as a "callback" by the MultiThreader. The threading library will call this routine for each thread, which will delegate the control to ThreadedGetValue().
