Miscellaneous Issues
Most of these issues were identified by Brad Davis.
CovarianceCalculator
- Known Mean versus estimated mean (incorrect equation: N versus N-1)
- Concept of Covariance: http://en.wikipedia.org/wiki/Covariance
- Sample Mean and Covariance: http://en.wikipedia.org/wiki/Sample_mean_and_covariance
Distance Metric
- Room to expand to other metrics (1_1, 1_inf, Mahalanobis)
Distance To Centroid Membership Function
- Why is 1_2 distance hard coded ? as opposed to using a distance metric ?
- Title centroid is unnecessarily narrow
- Why not a generic Distance Membership Function where metrics are plugged in ?
Distances
- itkEuclideanDistance
- itkMahalanobisDistanceMembershipFunction
ImageToCoocurrenceListAdaptor
- This is not really an adaptor, it generates new data.
- Should it be called Generator ? or Filter ?
ListSampleBase
- Very lightweight, probably unnecessary
- Only provides a Search() method, and this method probably shouldn't be there
NeighborhoodSampler
- Sample with spherical (1_2_ neighborhood)
- Allow other metrics ?
SampleAlgorithmBase
- Very lightweight, no obvious benefit
- Is it a candidate for deprecation ?
