Noise removal from background
显示 更早的评论
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.

Here's the enhanced image
after processing of which gave me the image specified within the question. I basically used adapthisteq() function on this image
to lay more emphasis on arteries which gave me the enhanced image. Is there any other way of enhancing it which would emphasize arteries while decreasing the background noise?

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.

You're welcome. Mark this, and any other of your several other questions that you're done with as "Accepted".
