Results from the morphology module were compared against output from the corresponding MATLAB functions, as applied to the lena test image. This image does not conform to the Debian Free Software Guidelines and had to be removed. The output is now tested against results generated with the current version of scikit-image (0.12.0), which is known to be correct due to the comparison described above.
