Hello Simon, Thanks for the quick response. I made some changes and sent you a pull request. However, because of the changes I made, I'm now having some problems in rtk::LUTbasedVariableI0RawToAttenuationImageFilter::BeforeThreadedGenerateData(). I tried to solve it using typename, but it seems to be unsuccessful. Could you please have a look? The I0EstimationProjectionFilter seems to work now.

I guess you should replace all "unsigned short" in the two code files by InputImagePixelType which is already defined in the header. I would also advise a code review, for example 16 line 33 of rtkI0EstimationProjectionFilter.hxx should be replace by std::numeric_limits<http://en.cppreference.com/w/cpp/types/numeric_limits><InputImagePixelType>::digits. I0EstimationProjectionFilter is based on a histogram analysis. Using 2^16 bins for unsigned shorts or 2^32 for unsigned int is too large so bitShift is used to reduce the number of bins to, e.g., for unsigned shorts, 2^(16-bitShift) bins. If you can't figure it out, let us know. If you do, please share your dev!

However, the input for SetMaxPixelValue requires an unsigned short, so I can only set a maximum value of (2^16)-1, which is not enough. Is there a possible solution/workaround for this? Could you also tell me what the bitShift represents in rtk::I0EstimationProjectionFilter? Thanks in advance.
