The design of a distributed image processing and dissemination system
The design and implementation of a distributed image processing and dissemination system was undertaken and accomplished as part of a prototype communication and intelligence (CI) system, the contingency support system (CSS), which is intended to support contingency operations of the Tactical Air Command. The system consists of six (6) Sun 3/180C workstations with integrated ITEX image processors and three (3) 3/50 diskless workstations located at four (4) system nodes (INEL, base, and mobiles). All 3/180C workstations are capable of image system server functions where as the 3/50s are image system clients only. Distribution is accomplished via both local and wide area networks using standard Defense Data Network (DDN) protocols (i.e., TCP/IP, et al.) and Defense Satellite Communication Systems (DSCS) compatible SHF Transportable Satellite Earth Terminals (TSET). Image applications utilize Sun's Remote Procedure Call (RPC) to facilitate the image system client and server relationships. The system provides functions to acquire, display, annotate, process, transfer, and manage images via an icon, panel, and menu oriented Sunview{trademark} based user interface. Image spatial resolution is 512 {times} 480 with 8-bits/pixel black and white and 12/24 bits/pixel color depending on system configuration. Compression is used during various image display and transmission functions to reduce the dynamic range of image data of 12/6/3/2 bits/pixel depending on the application. Image acquisition is accomplished in real-time or near-real-time by special purpose Itex image hardware. As a result all image displays are highly interactive with attention given to subsecond response time. 3 refs., 7 figs.
