Imagej

In arbitrary units, I need in pixels estimations for:

Height of the vase H

Top diameter of the vase Dt

Bottom diameter of the vase Db

Mean diameter of a hazelnut Dh (measuring a few of them)

Packaging factor F… something arround .6? I’m sure there is a better way of estimating it. Like counting air and hazelnut areas on the image but I’m not sure how to correlate 2D to 3D in this case.

The volume of the vase is Vv (H,Dt,Db)

The volume of a single hazelnut Vh (Dh)

N = Vv F / Vh
