[Insight-users] MutualInformationImageToImageMetric

[Luis Ibanez]

Hi Malempati:


1) Read the ITK Software Guide

      http://www.itk.org/ItkSoftwareGuide.pdf

    in particular the Image Registration chapter.


2) Make sure that your images have valid values
    of image origin and image spacing

3) Make sure that you initialize the Transform
    parameters

4) Add an observer to the Optimizer, and print
    out the values of the metric and transform
    parameters at every iteration.

5) Identify how many iterations you manage to
    run before you get the error message.



The error means that the Fixed and Moving images
have such small overlap that the registration
process can't continue.

The problem may be caused by:

a) incorrect image information
b) bad initialization
c) poor choices in the optimizer parameters



   Regards


      Luis
