   If you're classifying standard shapes like these, 2 or 3 good shape features   
   are more than enough, for   
   example number of corvers and principal inertia axes ratio (max/min) for   
   symmetry. If you still have   
   problems with the accuracy, perhaps the classifier you're using is not robust   
   enough (try using simple   
   NN after some tests with MDC).
