What I'd do is to binarize your image then label it and call regionprops(). Get things like the volume (area), bounding box, surface area (perimeter), etc. and see which of those is close to the values you'd expect for a perfect sphere..

Then calculate the surface area and the volume and compute the sphericity. See Wikipedia for the formula: http://en.wikipedia.org/wiki/Sphericity
