Filling gaps in binary images

I have a binary images of tree clusters, when I imshow(BW), some single trees are separated from the main cluster by 1 pixel. Is there a way to make single trees to be part of the nearest cluster. I've tried bwfill, didn't work.

Can you post the image...

If it really is just one pixel, then try this:

BW2 = bwmorph(BW, 'bridge');

If it is more than one pixel, then take a look at IMCLOSE. This will affect the entire binary boundary in the image, however.

This seems to work. Thanks
