[Insight-users] How to use Statistic Image Filter

[Bradley Lowekamp]

Hello,

You only stated that it "makes the program crash". That is really insufficient information for me to really know what is going on. Did your program seg-fault? Was an C++ exception thrown? Was it a divide by zero? What was the output?

I thought there may be some C++ exception thrown in the class by I don't see one:

https://github.com/Kitware/ITK/blob/master/Modules/Filtering/ImageStatistics/include/itkStatisticsImageFilter.hxx

I am going to guess there is an issue with you C++ code which tries to use the filter.... Also are you sure you are not using the LabelStatisticsImageFilter?

Brad

However, I faced a problem: when the segmentation is empty, the filter doesn't work saying that the number of voxels is 0, but it make the program crash instead. How can I properly evaluate if there are no voxels segmented in order to avoid the crash of the system?
