These cases are posted for those who wish to practice the "Diagnosis Accurate" Kittlerian algorithm. That is the long algorithm on the poster that is available from me at email@example.com
Please do your analysis stepwise following either the "one pattern" or "more than one pattern" arm of the algorithm as appropriate. I will post the answers in a few days. If you want them earlier send me an email.
Alan and I will respond to any questions you ask to the best of our ability. Harald may also respond when possible.
