Christian Kofler from the Image Understanding and Pattern Recognition Group in Keyserslautern has created a small GUI for FIRE called FireWatch. You can grep it from their site. (local mirror). FireWatch already supports the submission of images and to select regions from images for query which is not yet supported by the current version of FIRE. This feature has been developed by the Image Understanding and Pattern Recognition Group in Kaiserslautern and will soon be included in the main FIRE.

C# library for the FIRE protocol

Piotr Boninski from Warsaw University of Technology has implemented a C# library to access FIRE servers. All library stuff is in FireBrowser namespace, test application is in FireTester, the code is really small, so all files are in one folder (lib files are with *is* prefix) You need C# 2 compiler because of generics and partial classes (p. c in test app only) The library does not support all fire features, but feel free to enhance it :) Available from:
