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.

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