[ITK-users] SimpleITK JAVA ImageSeriesReader and PatchBasedDenoisingImageFilter and 4d images

[Lowekamp, Bradley (NIH/NLM/LHC) [C]]

I would look at the python examples and usage for reference:

https://github.com/SimpleITK/SimpleITK/blob/master/Examples/Python/DicomSeriesReader.py
https://github.com/SimpleITK/SimpleITK/blob/master/Examples/Python/DicomSeriesReader2.py

https://github.com/SimpleITK/SimpleITK/blob/master/Examples/Python/CMakeLists.txt#L73-L89

HTH,
Brad
