Hi,

I am trying to calculated Histogram based on the Fixed Bin Size (as opposed to giving the number of total bins). Is that possible in ITK?

Reference: [https://ibsi.readthedocs.io/en/latest/03\_Image\_processing.html?highlight=fbs#fixed-bin-size](https://ibsi.readthedocs.io/en/latest/03_Image_processing.html?highlight=fbs#fixed-bin-size)

Thanks,  
Sarthak

You can accomplish that by setting the number of bins and minimum and maximum values. [Example](https://itk.org/Doxygen/html/SphinxExamples_2src_2Numerics_2Statistics_2HistogramCreationAndBinAccess_2Code_8cxx-example.html#_a1).

`BinSize=(Max-Min)/Number`
