Detailed Description

Compares Histograms between two images to be registered to a Training Histogram.

This class is templated over the type of the fixed and moving images to be compared.

This metric computes the similarity between the histogram produced by two images overlapping and a training histogram.

It is to be sub-classed by the method of comparing the histograms.

Generally, the histogram from the training data is to be computed in exactly the same way as the histogram from the images to be compared are computed. Thus, the user can set the interpolator, region, two training images and the transfrom and the training histogram will be formed. OR, the user can simply calculate the training histogram seperately and set it.

Warning:

The Initialize function does nothing if the training histogram already exists. Thus repeated calls to the Initialize function do nothing after the first call. If you wish the training histogram to be re-calculated, you should set it to 0.
