[Insight-developers] how to provide A2D2 denoising code?

[Kris Zygmunt]

Hello!
     I am (finally!) ready to provide the A2D2 denoising code and just  
wanted to discuss the best way to do so.  I will create a gerrit topic  
called a2d2-denoising and put my changes there.  I think it makes the  
most sense to create a new Denoising module in Filtering, but please  
let me know if I should put the code elsewhere.  I have the following  
files:

denoising filter hierarchy that will be dependent on
ITKStatistics, ITKCommon, vnl, ITKImageStatistics, ITKImageGrid,  
ITKTransform, ITKImageFunction, ITKImageAdaptors
This hierarchy should be in Filtering somewhere, but does it go into a  
new module (called Denoising?) or an existing one?
itkPatchBasedDenoisingBaseImageFilter.{h,hxx}
itkPatchBasedDenoisingImageFilter.{h,hxx}
<associated test code will go in the associated test directory>


Image to sample adaptor to be put in the Modules/Numerics/Statistics  
area
itkImageToNeighborhoodSampleAdaptor.{h,hxx}


Generic subsampler hierarchy that I think fits in the Modules/Numerics/ 
Statistics area
itkSubsamplerBase.{h,hxx}
itkRegionConstrainedSubsampler.{h,hxx}
itkSpatialNeighborSubsampler.{h,hxx}
itkUniformRandomSpatialNeighborSubsampler.{h,hxx}
itkGaussianRandomSpatialNeighborSubsampler.{h,hxx}

It seems like Modules/Numerics/Statistics is rather large, are there  
any plans to split this into smaller modules?  What is the recommended  
way to include vnl in CMake for ITKv4?

Thanks!
Kris
