Content-based visualization and user-modeling for interactive browsing and retrieval in multimedia databases
A method for visualizing multimedia objects assigns a feature vector to each multimedia object. The feature vector of each multimedia object is reduced to a location vector having a dimensionality of a display device. A cost function is evaluated to determine an optimal location vector for each multimedia object, and each multimedia object is displayed on a display device according to the optimal location vector. The reducing can use principle component analysis. In addition, a relevance score can be determined for each displayed multimedia object, and the multimedia objects can than be visually enhanced according to the relevance score.
