Features value (mean and variance)


Sorry, I have a question, why mean value and variance value are big. For example, I’m working with DICOM abdomen images and I segmented these in 3D slicer and I converted to .nrrd but when I apply pyradiomics the mean value is 133. I don’t have idea what is the range and I whan to create an histrogram but I tried it and I failed. Help me please
