<div>Hi Bob,<br>
<br>
You can do this using itk filters in the following order:<br>
<br>
1. Use an itk::HistogramMatchingImageFilter to do histogram
equalization.<br>
2. Use an itk::ResampleImageFilter to map one volume spatially to
the other.<br>
3. Use an itk::AddImageFilter to add the result of Step 2.<br>
4. Use an itk::MultiplyByConstantImageFilter on the result of Step
3 to create the average (there may be a filter that combines Steps
3 and 4).<br>
