[Insight-users] ImageRegistration2 problem.

[Luis Ibanez]

Hi John,


Cygwin used has a problem for running the random number
generator that is used by the Mutual Information metric.

This has been fixed now.


The example:

          ImageRegistration2

is tested nightly

http://www.itk.org/Testing/Dashboard/20050517-0500-Nightly/TestDetail/__Examples_Registration_ImageRegistration2Test.html

and it is consistently passing in all platforms.

The typical output that you should see is in Cygwing is:

http://www.itk.org/Testing/Sites/dash14.kitware/Win32-cygwin331/20050517-0500-Nightly/Results/__Examples_Registration_ImageRegistration2Test.html



number of samples = 567
0   0.291543   [0.105135, 0.090224]
1   0.260628   [0.161649, 0.157256]
2   0.270509   [0.320506, 0.209221]
3   0.316618   [0.422436, 0.283459]

...

198   0.607511   [12.9989, 16.8214]
199   0.603641   [13.0552, 16.9111]
Result =
  Translation X = 13.0552
  Translation Y = 16.9111
  Iterations    = 200
  Metric value  = 0.603641





You should probably update your version
of ITK in order to  use CVS.



Regards,



    Luis
