Abstract
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.
