1. A multimedia system comprising:

  • a query module generating a query in a plurality of media modalities;

    a database including a plurality of matrices, each matrix corresponding to one of the media modalities, wherein each matrix builds a correlation between the corresponding media modality and another media modality;

    an object detection module extracting a first plurality of object features from the query and a second plurality of object features from the database wherein the first plurality of object features and the second plurality of object features are extracted from media representing different modalities; and

    a processor coupled to the object detection module, the processor being trained on the plurality of matrices of the database to maximize a bi-directional correlation of cross-modality media using sample data, the processor determining a correlation between the first plurality of object features and the second plurality of object features and to retrieve those items from the database which have a correlation at least equal to a predetermined maximum degree of correlation.
