measure diameter (tickhness) from binairy picture

[Chantal]

Hello,

I'm trying to measure the thickness of some vains in a picture, first I made sure that the picture only excist of 2 colors

one for the vains and one for the background, now I'm trying to make a program which measures

the diameter (don't know how to spell it in englisch) of the vains, also the thickness.

Does anyone have an idea?

thanks!

See tag for a picture

Using edge detection you can do this

Yes, I know that, but it has to measure it without a user doing anything.

It has to recognize the vains and than measure te biggest diameter and the smallest.

Do you also have ideas for that?

Circle detection returns this. Can something be deduced from this?

I'll have to try, is that a normal example?

Do you mean a normal practice? I dont think so. But the object being so irregular and the result clearly shows the bigger diametermeans bigger nerves and vice versa give it a try..

I can't find it, but if it's possible to klik on each item and see how big it is,

I can work something out, than it will be great 🙂

Could you please add the program you used?

Thanks!

Hmm... still can't find it, where must I look to get the function circle detection? 🙂
