  1. Jeremy Leakakos George Hodgson Elizabeth Leib Douglas Krofcheck David McClelland Team Haplocyonopsis Pro Quo Books Book Cover Scanning System

  2. Synopsis • Who is Pro Quo Books? • What is the problem we need to solve? • You'll have a list of 30 million books.  You'll be given an image of a book, and you need to find out which of the 30 million it is... in 9 seconds. • What are we doing about it? • Why is this a difficult problem?

  3. Deliverables • Book cover preprocessing library • Book cover identification library • Test application

  4. Requirements Elicitation • Initial sponsor meeting • Conference calls • Application prototype • Performance requirements • 9 second time limit to identify a book • 20% identification rate with 90% confidence

  5. Technologies • C# / Visual Studio • MySQL • AForge.NET • Open source image processing library

  6. Technical Process • Evolutionary delivery • Incremental development • 2-3 week increments • Test app increment • Prototype increment • Product increment

  7. Evolutionary Delivery

  8. Metrics • Effort: Time tracking • Team and individual • Progress: Average time taken to identify a book • Progress: Number of true positives vs. number of false positives

  9. Testing Strategy • Test application • Deliverable • Testing platform • Simulate production environment • Input rate • Time threshold • Database size

  10. Test App Metrics Graph

  15. Risks • Unfamiliar domain • Image processing • Inadequate testing material • Test database not large enough • Miscommunication • Misunderstanding of terminology

  16. Design • Pipe and filter architecture • Start with filters to whittle down the dataset • Finish with identification algorithms

  17. Sequence - Scanning

  18. Sequence - Preprocessing Fly Fishing

  19. Sequence – Database

  20. Sequence – Imaging 0.093 chance of matching

  21. Sequence - Result

  22. Progress so far… • Test application • Multiple functional filters and identification algorithms • Preprocessing algorithms • Solid plan for spring quarter

  23. Reflections • The good stuff • Communication • Test application • Working filters and identification algorithms • Well-defined scope

  24. Reflections • The not so good stuff • Time estimation • Production problems

  25. Spring Quarter • Prototype increments • Products increments • Finish development
