imshow(Img)
You can also filter based on area of objects
Img = bwareafilt(imbinarize(Img),4,'largest'); % keep the 4 largest objects
imshow(Img)

Depends on exactly what that means.
- Do you want to simply remove small blobs?
- Or do you also want to remove a small protrusion that is sticking out of the side of a much larger rectangle.
For case 2 you might try imopen, though be careful for changes to the shape you don't want, especially near the corners or protruding blobs.
