• Address Run-time memory issues
  • Purify reports
  • Valgrind reports

CVS Tagging

Insight Journal Papers to move to Review

• Label object representation and manipulation with ITK (65 classes). Provides most of the features of A Label Geometry Image Filter for Multiple Object Measurement, but there are still a few ones not covered.

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.
