I would like to remove noise shown marked in red circles.

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.

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