I have this image

which I obtained after enhancing in order to make the artery clearly visible. I need to know how would I be able to remove the background noise without disturbing the details within the artery itself. I just want to obtain a black background or a background with reduced noise compared to the current noise present. P.S. Artery is represented by the two thick lines going to the right.

Looks like you'd have to "hand paint" it, because I can't really tell what's noise and what are valid blood vessels.


I suggest you look at section 20.10 here VisionBib to find out the lastest and best radiographic noise reduction techniques or artery following/tracing methods.
