I’m trying to get a list of properties of images using the regionprops function, but it seems that the function always return a full list of properties.

the question is how do I know which properties are 2d only, and which are for both 2d and 3d?

For example, if my input image is 3d, and when calling `region[0].eccentricity`

I get an error saying eccecntricity is not implemented …

Also, another question is that, when I specify ‘convex_image’ property in the regionprops_table function for a 3d image, I get a qhull error

```
scipy.spatial.qhull.QhullError: QH6013 qhull input error: input is less than 3-dimensional since all points have the same x coordinate 0
```

I have no idea on why the error occurs and how I can fix it… any help would be much appreciated

thanks
