[Insight-users] KullbackLeiblerCompareHistogramImageToImageMetric

[jef vdmb]

Hi,

I am trying to find out which metric behaves the best for my multi modal 
registration problem. The images are a 2D US and a 3D MR (should you have 
any suggestions, based on their modality).

I am plotting the metric value for all multi modal metrics available, but I 
am having problems understanding how to use the 
KullbackLeiblerCompareHistogramImageToImageMetric. In the SoftwareGuide, it 
seems you only need your two images. When I go to the Doxygen pages however, 
a "training histogram" is mentioned.

Could you please clarify the use of this metric, any parameters that need to 
be set (besides epsilon), or known preprocessing improvements (like 
normalisation).

Thank you,

Jef
