Abstract. In this paper we show how modern shared-memory parallelization techniques can gain nearly linear speedup in content-based image retrieval. Using OpenMP, few changes are applied to the source code to enable the exploitation of the capabilities of current multi-core/multiprocessor systems. These techniques allow the use of computationally expensive methods in interactive retrieval scenarios which has not been possible so far. In addition, these ideas were applied to a clustering algorithm where substantial performance improvements could be observed as well. 1
