Measuring objects in an image

[Sarmad Rehan]

Hi everyone,
I am a new user of ImageJ and want to measure wall thickness of some blood vessels sections and their luminal diameter (from capture microscopic images).
I can measure thickness by drawing lines manually, but i want the software to do it automatically.
Can some one guide me doing this?

This problem is called "automatic segmentation", and has driven
generations of scientists to insanity.

Basically, there is no general solution, but you might be lucky in that
your data could be handled by some automatic segmentation algorithms.

However, it is very, very hard for me to evaluate if that might be
possible without seeing your data.

Hi dear,
U can view the images from the link below:

One (illustrated bllod vessel) is a textbook sort of image. You can recognise MEDIA and LUMINAL DIAMETER here, which I am trying to measure in the representative image (1 200x).

I'm afraid there is not an ease solution for you.

In fact, I think finding this answer is a valid topic for a master's
thesis... You can contact a research group and invite them to join you in a
cooperation work, if it's important to you. Image processing research groups
are always looking for some "real world problems" to solve.

Good luck,
