regionprops() 'BoundingBox' would give you the bounding box without any problems. You could also request the 'Eccentricity' and use that to choose between the two output regions. You might also want the 'Image' property.

regionprops() is going to give you a structure array of length 2. You can examine the properties returned to decide which of the two each one refers to.
If you have a newer version of MATLAB, R2014b or later, you can use bwareafilt() and ask to keep the 1 'smallest'
