Architecture of a networked image search and retrieval system
Roger Weber, J. J. Bollinger, T. Gross, Hans‐Jörg Schek · 1999
Large scale networked image retrieval systems face a number of problems that are not fully satisfied by current systems. On one hand, integrated solutions that store all image data centrally are often limited in terms of scalability and autonomy of data providers. On the other hand, WWW-based search engines proved to be fairly scalable, and data providers retain their autonomy. However, such engines often confront users with links to servers that are not available or to images that no longer exist, i.e., they are unable to keep their meta-database consistent with the repositories' contents. Furthermore, existing solutions often neglect the cost of image delivery. The considerable variations in the effective bandwidth in today's Internet lead to highly unpredictable response times, which are often intolerable from the user's point of view.
