Try imclose() to merge nearby regions into the same region.

It basically dilates the binary blobs by one or more layers, making it "grow" and possibly connect to other blobs. This will also make the blob boundaries smoother. Then it erodes that by the same amount to get it back to the same size. The boundary will be smoother than the original and any connections made to adjacent blobs will still be there. So basically it will merge blobs and smooth the outlines.
