It would help if you posted images of the orignal and the result of
bwboundaries.

You might consider using regionprops, and then using area, perimeter and
other such metrics to make your decisions about the shape. For example
different geometrical shape generally have different area/perimeter ratios.

Sorry. I don't reinvent wheels, or regionprops() either.
If you want to reinvent regionprops, you're on your own.
Good luck.
