DISIMA Image Database Management System


The primary objective of this project was to design and develop a distributed image DBMS, which, on the one hand, provides mechanisms and techniques for efficient image compression, fast image transmission, and flexibility in content-based querying of images; and, on the other hand, provides a convenient and uniform interface for global users to access image data from multiple, disparate source repositories. More specifically, the following objectives were established at the outset:

  1. Design of an interoperable integration framework based on the object-oriented methodology for distributed image database management, which provides typical DBMS services for uniform access to multiple, disparate image repositories.
  2. Development of new image database indexing techniques to support flexible access to the images from multiple source repositories, and to enable global users to query remote image databases beyond the set of pre-defined query patterns.
  3. Exploration and development of powerful and efficient image compression algorithms that enable fast and high-quality compression of images.
  4. Provision of facilities to support progressive transmission and selective transmission of images across networks.


While the project addressed all of these objectives to a certain extent, the focus was on the database aspects of image management (objectives 1 and 2) rather than the image processing issues (objectives 3 and 4).
