The work on adaptive object detection explores a new paradigm in dynamic parameter selection, by selecting thresholds for object detection to maximise agreement between pairs of sources. Object tracking, a complementary technique to object detection, is also explored in a multi-source context and an e±cient framework for robust tracking, termed the Spatiogram Bank tracker, is proposed as a means to overcome the di±culties of traditional histogram tracking. As well as performing theoretical analysis of the proposed methods, speci¯c example applications are given for both the detection and the tracking aspects, using thermal infrared and visible spectrum video data, as well as other multi-modal information sources.  \nList of publications  \n² C. ¶O Conaire, N.
