Proposals:Refactoring Statistics Framework 2007

ITK: Statistical Framework Refactoring

Motivation

Recently it has been found that certain characteristics of the Statistical Framework API could be improved in order to provide a more consistent inteface.

In particular, issues have been pointed out regarding the following topics

• Iterators
• Samples versus Subsamples
• Statistical calculator integrated into the pipeline

Tasks

The proposed refactoring will include the following specific tasks

• Review all iterators used in the Statistics framework and add tests for their functionalities until bringing their code coverage to 100%
• Restructure the impolementation of the Subsample class, to make sure that
  • It can be used in any place where a sample can be used.
  • Subsampling can be nested without breaking the consistency of the statistical operation.

Schedule

The refactoring tasks will be initiated on March 23rd and will be completed before April 15th 2007
