Intelligent Visual Interaction on Multimedia Database System TRADEMARK

摘要

The report describes the multimedia database system TRADEMARK. The system includes image processing facilities as the primitive data operations. It provides: (a) intelligent image data registration and indexing by layout analysis and graphical feature vectors (GF vectors); (b) similarity retrieval by a visual key; and (c) multimedia document formatting of retrieved data. Similarity retrieval in the system also permits a hand-written sketch as a visual key. The subjective feature space (SF space) and its robust SF space are constructed by the discriminant analysis. Its ability in similarity retrieval is also experimentally evaluated.
