Comment (Feb. 2, 2008, R Brooks)

With regard to the class for serial transformations, this is an excellent and useful idea. However, the paper linked to here does not support the registration framework, where as another paper on the same topic does. [65] That paper, however, has its own set of limitations. I think that a class for serial or combined transforms is a valuable addition. However, I worry that if done prematurely, we would be stuck with a limited interface due to ITKs backwards compatibility policies. I think some serious thought should be put into how this interface should work before committing to a particular implementation.

At the very least i think that any such class should support:

  1. The registration framework - ie - proper Jacobians
  2. An arbitrarily long chain of transformations
  3. The ability to have some fixed and some parameterized transforms - by this i mean that some transformation parameters do not appear in the GetParameters and Jacobian methods.
  4. Some sort of intelligent interaction with the transform reader and writer classes.

I suppose that I should kick myself a bit, for not having reviewed either of these papers. I'll post this to the list as well and see if it spawns discussion.

Insight Journal Papers to move to Review

Review Articles to be Moved

Current suggested list:

  • itkTransformReader
    • (and associated factories)
  • Multi-threaded Registration
  • Consolidated Morphology
    • These classes need a code walk through to review Method names, especially internally used names. There are several that do not conform to ITK naming conventions. (e.g. itkBoxUtilities: setConnectivityEarlyBox
  • Binary Functor Filters
    • AddConstant, DivideByConstant, MultiplyByConstant, SubtractConstantFrom

Check-list for Moving Code from IJ to Review and from Review

For IJ Articles To Review

  • Responsible developer should add a review before moving into local copy of Review. Please provide authors with feedback regarding changes that were made to conform to ITK style/documentation etc.

For Adding Images to Input or Baseline

  • Images should be SMALL.
    • The source tree is not an image database, but a source code repository.
    • Adding an image larger than 50Kb should be justified by a discussion in the Developers list
    • Make sure that you use the "cvs add -kb" option when adding binary files to the CVS repository.
  • Regression images should not use Analyze format unless the test is for the AnalyzeImageIO and related classes.
  • Images should use non-trivial Metadata.
    • Origin should be different form zeros
    • Spacing should be different from ones, and it should be anisotropic
    • Direction should be different from Identity

For Moving Code From Review

  • At least one independent (other than contributor) should sign off on the API
  • Coverage should be as close to 100% as possible.
    • and never lower than 90%.
    • For example, itkTransformIOBase.cxx is only at 63% coverage. Should be easily fixed by adding a Print() to one of the tests.

For All

  • Check all comments for proper English
  • Should pass KWStyle. IJ articles should be checked with KWStyle before checking into repository.
  • Should pass PrintSelf. IJ articles should pass PrintSelf check before checking into repository.
  • ITK_EXPORT should appear in each class definition. This triggers the PrintSelf checker.
  • Replace itkGetMacro with itkGetConstMacro.
  • Header file should contain Insight Journal citation
    • Using the "handle" link.
  • Use vcl verions of all transcendental functions.
    • For example, itkGaborKernelFunction used sin() and cos() rather than vcl_sin() and vcl_cos().
  • Progress should be present for all filters. Use itk::SimplerFilterWatcher to exercise progress and PrintSelfs.
  • When appropriate, class should handle image directions. Tests should use non-default values for origin, spacing and dimension.
    • GaborImageSource did not provide methods to set/get directions.
  • Regression tests names should when possible have the same name as the test.
  • Exceptions should be descriptive and provide as much information as possible
  • Member data should be private with access if required through Get methods.
