  1. Leader: prof. Pavel Zezula zezula@fi.muni.cz Members: Dr. Michal Batko Dr. Vlastislav Dohnal Dr. David Novak Dr. Jan Sedmidubsky xsedmid@fi.muni.cz Ph.D. students: 5 MUFIN: Large-scale Similarity Search Faculty of Informatics Masaryk University Brno, Czech Republic MUFIN: Large-scale Similarity Search

  2. MUFIN Search Engine data & queries index structure infrastructure MUFIN Research • MUFIN - a universal similarity search technology • Research directions in: • Core technology • Applications • A style of computing Scalability P2P structures Extensibility metric space Performance Tuning MUFIN: Large-scale Similarity Search

  3. MUFIN Search Engine data & queries index structure infrastructure Core Technology • Development of the MUFIN core technology New query types Flexible sub-sequence matching Efficient multi-feature processing More scalable, reliable, robust Multi-layer architectures Self-organizing architectures Performance Tuning MUFIN: Large-scale Similarity Search October 28, 2011

  4. Applications • Images: • Sub-image retrieval • Ranking • Annotation • Categorization • Benchmarking • Biometrics: • Face recognition • Fingerprint recognition • Gait recognition • Signals: • Audio recognition • Time series similarity • Videos: • Event detection MUFIN: Large-scale Similarity Search

  5. A New Style of Computing • From the project-oriented approach towards similarity cloud • Advantages: • Cloud makes similarity search accessible to common users • Computational resources are shared – users don’t need to maintain any hardware infrastructure • Users don’t need to care for the OS, security, software platform, etc. MUFIN: Large-scale Similarity Search

  6. Query Answer: Prototype Examples: Images Cornflower Photo from my trip to highlands purple • blue • color • plant • beauty • nature • garden • petals • hydrangea • weed Extract keywords from similar images Search by visual similarity • Image similarity search demo (100 million images) http://mufin.fi.muni.cz/imgsearch/ • Sub-image retrieval http://mufin.fi.muni.cz/subimages/ • Annotation http://mufin.fi.muni.cz/annotation/ Iris in the botanical garden Unknown violet flower MUFIN: Large-scale Similarity Search

  7. Prototype Examples: Biometrics & Signals • Face recognition http://mufin.fi.muni.cz/faces-feret/ • Time series http://mufin.fi.muni.cz/subseq/ Query Answer: MUFIN: Large-scale Similarity Search
