I would not call those features noise. And a quick scan of the code looks like you're just setting the blobs to zero. Is that what you mean by "remove"? And your fmax usage seems very weird.

@Image Analyst I agree with you, it is not a noise, but in my case it is an unwanted information, which I would like to remove.

I would be grateful, if you could give an answer or an idea for one of my questions?

See attached m-file.

You can increase thet threshold or run imdilate() on the binary image if you want to enlarge the blobs.
