[Insight-users] [ITK Community] ImageRegistrationHistogramPlotter Not Working

[Emma Saunders]

Hi ,

Im in putting two 3D float volumes and change the pixel and dimensions
accordingly.

I may be a little confused here, is the RescaledOutputImage the 2D
histogram or the image itself, when I use

 typedef itk::Image< unsigned char, 3 > RescaledOutputImageType;

Things seem to work?
