Fruit symmetry analysis

[EJ]

Hi,
I've only just discovered ImageJ, and hope to use it as a tool for my thesis. I have been applying treatments to strawberry plants and want to see how this may affect the symmetry of the fruit produced. I have images of the sliced fruit scanned in.
I am sure I can use ImageJ to analyse this somehow, but the plugins I looked at didn't seem appropriate.
Does anyone know how I could use ImageJ to analyse the symmetry of the fruit?
Thank you for any help.

Hi Ellie,

I expect that ImageJ should work, perhaps by using the shape descriptors. It always depends on the quality of the images though. Are you able to post an image somewhere? Also, your slices would need to be consistent, e.g. directly through the middle in cross and transverse sections.

If you want to look at the 3D shape by building a stack with the slices, that would be a little more complicated.

Kind regards,

Jacqui

I am curious about this. How do you define a measure for fruit symmetry? Is there an existing standard or accepted procedure? I can imagine that a major challenge is to find the optimal axis of symmetry / mirror plane: the axis/plane that maximizes your symmetry measure. I cannot recall any plugin that can do this, but maybe I am wrong.

Symmetry of volume or projected area.  If projected area from below, SD of radial symmetry?  Pics like this??
