Hi scikit-image users/devs, I'm using skimage.measure.regionprops and I'm little bit confused about a result I get with it. I'm working with a zstack of a microscopy image that I have segmented/label and I'm trying to get the mean intensity of the labeled region: region_props = measure.regionprops(label_image, intensity_image)

If now I do: for prop in region_prop: print('x', prop.mean_intensity)

...

print('y', np.mean(prop.intensity_image))

...

prop.mean_intensity and np.mean(prop.intensity_image) give me different value, which confuse me. Can someone help me understand why I'm getting something different? Thank you in advance for your help. Sincerely, Cedric
