The other area to look into would be mathematical morphology (MM)(Options under the Process-Binary menu item in ImageJ. Open, close, erode, dilate - that sort of thing), MM was developed with just your sort of problem in mind. There are books by Serra and Soille in this area (which is pretty well developed). Sorry not to be more helpful - this borders on what I'm interested in but I don't have the sort of thing you're after. regards Ian ====================== Dr Ian Hopkinson Department of Physics UMIST Sackville Street PO Box 88 Manchester M60 1QD e-mail: [log in to unmask] phone : 0161 200 8881 fax : 0161 200 3941 http://personalpages.umist.ac.uk/staff/I.Hopkinson/default.htm ====================== -----Original Message----- From: ImageJ Interest Group [mailto:[log in to unmask]]On Behalf Of Gregor Baechle Sent: 15 November 2002 21:43 To: [log in to unmask] Subject: Re: Plugin for Calculation of Bone Structure Hello, I am working on the 3D pore structure of carbonates and I would be interested in 3D pore shape and volume characterization as well. I am using x-ray tomography and I try to find a plug-in which could perform things like pore size distribution and pore surface area. Please keep me informed in case you get something.

For the moment I haven't found a solution for the analysing of 3D reconstructed images, but I think we are looking for the same thing. best regards, Veerle Cnudde University of Ghent, Belgium ----- Original Message ----- From: "Hari Menon" <[log in to unmask]> To: <[log in to unmask]> Sent: Friday, November 15, 2002 9:01 AM Subject: Re: Plugin for Calculation of Bone Structure > I am also looking for a a Plugin which can be used to find pore size > distribution, pore volume and pore surface area in Xray Tomography 3D > reconstructed images.
