Design and implementation of a distributed database for color image storage and retrieval

摘要

Continuing advances in high speed computer network and distributed database technology have made possible new applications. One such application is ImageNet, a color image database and interconnecting network designed on a national scale. The concept of ImageNet includes several Database Nodes (DBNs) dispersed throughout the nation and interconnected via a high speed communications network. This work includes the design and implementation of a distributed database for color image retrieval and storage in the context of the ImageNet project. The system design for ImageNet and its distributed database are presented, and an implementation on multiple workstations was performed. In addition, a simple performance evaluation of the DBN implementation is shown, and suggestions for improving the next version of the DBN are given.
