unsupervised learning

[Aloysius Phillips]

Hello,

I would like to classify 2D shapes from cross sections using unsupervised learning. Does anyone have any advice about which attributes ImageJ can describe? The more the better. It doesnt matter if they are correlated. Also, any advice on unsupervised learning in general would be appreciated. Thank you.

Try the shape descriptor plugin at http://www.gcsca.net/IJ/ 
Shapes.html. It may be a start.

FracLac finds some attributes of 2d shapes, such as the fractal dimension (for complexity) and lacunarity (for heterogeneity), as well as some other morphometrics.  Its available here:
