See my Image Segmentation Tutorial and see how I get the bounding box. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

It gives you a structure array. Each structure in the array is a structure with field that correspond to the measurements you asked regionprops() to make. For example measurements(7) has all the measurements for blob #7, like Area, Centroid and BoundingBox: measurements(7).Area, measurements(7).Centroid, and measurements(7).BoundingBox.
