I don't know specifically about bubble counting but my first blush at 
how to do this would be to run an edge detection filter, smooth it 
somewhat with a simple kernel, perhaps one slightly weighted to make 
circles of whatever the average diameter of your bubbles are to fill in 
any 1 pixel gap type issues. Then go through and count the "holes" in 
the resultant image (look for closed polygons).
