Web10 de mar. de 2024 · 3. Multiply the volume and density together. Multiply your two numbers together, and you'll know the mass of your object. [1] Keep track of the units as you do this, and you'll see that you end up with units of mass (kilograms or grams). Example: We have a diamond with volume 5,000 cm 3 and density 3.52 g/cm 3. WebI would propose using a distance transform. So once you've got your labeled image you do: dt = ndimage.distance_transform_edt (blobs) slices = ndimage.find_objects (input=labels) radii = [np.amax (dt [s]) for s in slices] This gives the largest inscribed circle (or sphere in 3D). The find_objects function is quite handy.
