collections makes the management of the indexing structures com-
plex. Distributed and parallel processing is certainly a key-issue to
really attain the large-scale objective. Its role is to divide the compu-
tational effort of indexing and retrieval operations over a number of
CPUs and memory devices. Although feature extraction is somewhat
easily distributed over several CPUs with a coarse-grain strategy,
obtaining efficiently distributed indexing and learning procedures is
more challenging, especially in the context of multimodal retrieval.
The large-scale distributed indexing research ...
