  • Hans added a new test that is currently failing. It was written to show a problem with many high-resolution images:
    • The itkSparseFreqeuncyContainer, and the itkDenseFrequenceyContainer are using floating point values for their FrequencyType. I am not sure if the new statistics framework has the same issue.
    • In many common images of size 512x512x384 have backgrounds of all zeros with a count greater than the maximum that can be incremented to using 32 bit floating point numbers.
