Adapting metric indexes for searching in multi-metric spaces

Benjamin Bustos, Sebastian Kreft, Tomáš Skopal
2011 Multimedia tools and applications  
This paper presents a methodology for adapting metric indexes to multi-metric indexes, that is, to support similarity queries with dynamic combinations of metric functions.  ...  A recent approach that has been shown to improve the effectiveness of similarity search in multimedia databases resorts to the usage of combinations of metrics (i.e., a search on a multi-metric space).  ...  We showed how the methodology can be applied to two different metric indexes, yielding two novel indexing methods for multi-metric spaces, and how previously proposed multi-metric indexes fit into this  ...
