Abstract
This thesis discusses various aspects of digital image retrieval and management. First, we discuss user interface and visualization for digital image management. Two innovative systems are proposed. 3D MARS is immersive 3D display for image visualization and search systems. The user browses and searches images in 3D virtual reality environment. ImageGrouper is another graphical user interface for digital image search and organization. New concept, Object-Oriented User Interaction is introduced. The system improves image retrieval and eases text annotation and organization of digital images. Unlike the traditional user interfaces for image retrieval, ImageGrouper allows the user to group query example images. To take advantage of this feature, a new algorithm for relevance feedback is proposed. Next, this thesis discusses data structures and algorithms for high-dimensional data access. This is an essential component of multimedia data retrieval. The results of preliminary experiments are presented.
