Function similar to bwareaopen

 Is there any function similar to bwareaopen but to eliminate pixel greater than x?

When I used M3=bwareaopen(M2,250) --> This action eliminates in M2 the region less that 250 area. Bui if I want that the area greater than 8000 will be eliminated. What function can I used?

The following will remove any areas greater than 8000 pixels:

M3 = M2 & ~bwareaopen(M2,8000);

Another option would be to use regionprops() to get the area of every mask and then remove [stats.Area]>8000, but I think the above 1-line solution is cleaner.
