[Insight-developers] ImageToHistogramGenerator

[Miller, James V (Research)]

The statistics library was designed to operate on vector data. This 
is unfortunate because the first thing people try always seems to be
scalar data data.

There is an adaptor to convert scalar data to vector data. 

There is also an 

itk::Statistics::ScalarImageToHistogramGenerator<>

Hello,

I just tried instantiating

itk::Statistics::ImageToHistogramGenerator< itk::Image<float, 2> >

and got errors because the statistics code tries to access 
PixelType::ValueType in the image.  Is this code meant to work only with 
vector images?  I think this should use a numeric trait to get the 
scalar type for any pixel type.

Comments?
