Auskunft zu diesem Dagstuhl Seminar erteilt
Content based retrieval of multimedia documents containing text, image, audio, or video is of fundamental importance for a number of applications. This seminar brought together 22 participants from different areas like computer graphics, database and information systems, applied mathematics, audio retrieval, and computational geometry.
Altogether 17 talks were given, on a variety of topics. Yet, it was possible to identify some core problems that kept occurring in different contexts.
- How to define, and measure, the similarity between objects; how to implement efficient retrieval algorithms for finding the objects most similar to a given query.
- How to define semantics of multimedia documents, and how to enable semantic-based retrieval.
- How to decompose documents into segments, and how to perform segment-based retrieval.
These core problems should receive high attention in future research.
- Multimedia retrieval
- Shape analysis
- Feature extraction
- Metric design
- Mesh generation
- Knowledge representation
- Geometric matching
