    <div class="moz-cite-prefix">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>
