1- Do you know any software that I can apply watershed algorithm to 24 bit jpeg images?

2- I ve first tried ooding it and found this website which tells it in C# which I need exactly. http://weblogs.sqlteam.com/mladenp/archive/2008/02/11/Watershed-Image-Segmentation-in-C.aspx[^] But I couldn't handle it implementing the code into my the code I write. Do you have any advises on how to implement the code successfully?

You will find an applet there: http://bigwww.epfl.ch/demo/jwatershed/index.html[^]

Unfortunately, it only displays sizes up to 256 x 256.

Two caveats:

- the standard watershed transform is only defined for grayscale images, no color ones.

- you can be surprised by the results, especially with noisy images: the watershed transform strongly oversegments.

Yes it looks like it's over segmenting but that's why I needed it :)
Thank you, as well.

Solution 1

It gives you the full code!
If you "couldn't handle it implementing the code into my the code I write" then how do you expect people who can't see your code, much less modify it to do anything useful?

I assume this is your homework, and you just can't be bothered to try...

It gives me the full code, that's right but im not into computers and this is not my homework. I'm not even a student. That was just a careless answer.
All I need is the watershed result of 20 medical images I have. I do not need the codes, I do not have to code the software but I couldnt find any software that does that, so I have even tried coding it by almost knowing nothing about programming.

So, as my first question goes, do you know any software that does the watershed?

The closest thing I could find for you is this: the program you can use is ImageJ by National Institutes of Health (http://en.wikipedia.org/wiki/National_Institutes_of_Health[^]), see http://en.wikipedia.org/wiki/ImageJ[^], http://rsb.info.nih.gov/ij/[^].

You might need the plugin for this program for watershed calculations, see http://rsbweb.nih.gov/ij/plugins/watershed.html[^].
