1. MPII Joint Project Goals & ideas: department 1

2. Goals  cross departmental collaboration  strong outside visibility  external funding (DFG, VW-Stiftung?)  work packages / responsibilities  proposal within six months  duration ~ two years  spin off

3. Ideas  Shape retrieval  Peer2Peer photo repository

4. Shape Retrieval

5. Shapes Entertainment Biology Medical Engineering / CAD

6. Objectives  partial matching  matching of complementary shapes relevant for docking?  support for all kinds of shapes CAD models (sharp features), bio-molecules (flexibility, conformations), …  shape semantics (tagging, tag inference, …)  infra structure index to support multiple similarity measures, …

7. Similar projects  Princeton Shape Retrieval and Analysis Group  Remco Veltkamp’s group in Utrecht  Commercial products, e.g., SD&M.

8. Peer2Peer Photo Repository  the old days: take a few photographs, develop, label and store them show them to a few friends in the evening  nowadays: digicams  a lot more photographs are taken photographs are mostly stored on a computer very often remain unorganized (due to sheer amount) images are shared via the internet in photo communities

9.  1 st Goal: automated organization of photos avoid manual interaction if possible -- just download them from the digicam, and they're categorized (according to subject) allow for similarity search, e.g., display all images showing Kurt  2 nd Goal: Peer2Peer image sharing make whole portfolio online available allow P2P searches for similar images market place for photographs... Peer2Peer Photo Repository

10. Research Questions  similarity search based on image sequences  image search in P2P networks  automatic categorization/tagging of images  popularity-based caching of images  serialized watermarking of images

11. Similar Projects  Photo sharing communities like fotocommunity.de, photosig.com, flickr.com do not scale due to centralization unsatisfactory retrieval functionality  Image organizers like Picasa no image sharing manual categorization/tagging of images  Most related project: riya.com (Stanford spinoff) allows for automated tagging centralized webservice, though
