A method and system which enable a user to query a multimedia archive in
one media modality and automatically retrieve correlating data in another
media modality without the need for manually associating the data items
through a data structure. The correlation method finds the maximum
correlation between the data items without being affected by the
distribution of the data in the respective subspace of each modality.
Once the direction of correlation is disclosed, extracted features can be
transferred from one subspace to another.
