About

SIRET (SImilarity RETrieval) research group (SRG) was founded in 2006 at the Department of Software Engineering, Faculty of Mathematics and Physics, Charles University in Prague. SRG deals with database methods for efficient and effective similarity search in databases of complex unstructured objects. In particular, SRG is interested in three areas - general methods of indexing similarity (metric and nonmetric spaces), biological applications of the similarity search, and indexing image databases for content-based retrieval.
