There are functions bwareaopen() and bwareafilt() that could help filter based on size. If you have other characteristics that define noise, like shape or whatever, then use bwpropfilt(). You might also look at bwmorph() and options such as 'clean'. Or you could smooth boundaries with things like conv2() or imclose() if jagged boundaries are what you call noise. It just depends on what you call noise, and we don't know because you forgot to include your image.
