delete background

[Chantal]

Hello,

I would like to delete the background so I can measure some things,

I've tried some thresholds but they don't work good enough, some

little veins are not visible anymore after the threshold.

Has anyone an idea how to solve this?

Thanks!

Do gamma correction and then apply canny edge detection.

You do the canny and save the image apply threshold and do further processing. Try setting the appriate filter parameters this way.

So I will have a picture with only the edges?

or do I get it wrong 🙂

[muks]

Yes but you can always apply threshold and do morphological operations over that.

Oke, Thank you for the help! 🙂
