Measuring sphericity of a set of voxels. [message #67805]

Does anybody have ideas on how one could determine how close to
spherically symmetric a set of voxel intensities are?

The way I see it there are two separate questions:

1. how rotationally symmetric are the brightness values
2. how constant are the values as you get farther from the center

I am most interested in #1. But #2 is cool too!

Was thinking of getting the principal axes and checking how similar
they are to each other for Q #1... but I suspect there might be a
better way.

This is not strictly an IDL question, but I will be implementing your
suggestions in IDL and would apprciate suggestions on the
implementation too if you're feeling generous!

Many thanks,
Gianguido
