Moments of Inertia Query RoI Manager

Hi All,

This is a newbie question regarding the ‘moments of inertia’ function available in the 3D Roi Manager plugin. My question is what are the measurements provide? The results gives values for “Moment 1, Moment 2… etc. to Moment 5”, but looking at the description on the plugin website (http://imagejdocu.tudor.lu/tutorial/working/tutorial_for_3d_roi_manager) “3D Moments: shape descriptors based on order 2 moments” doesn’t really provide any detail… does anyone know of any more in-depth documentation to support this?

Thanks,
Jonny
