Re: particle analysis-Feret diameter

Hello,
I think that you have only one feret diameter, the maximum.
draw the convex hull and then compute all the distances between the points in
the hull.
What is the minimum? The smallest size hole through which the particle can pass?
How about a banana? Does anybody know of an algorithm that can compute the
smalles feret for an egg and for a banada?
