We present a jump-diffusion particle filter for tracking grouped and fragmented supra-threshold targets in visual data. The approach deals with multiple interacting targets in which single objects may yield multiple measurements (target fragmentation), and also for situations in which targets merge and move together. Data association, spatial grouping of features and spatial fragmentation are incorporated...
The Map Seeking Circuit (MSC) has been suggested to address the inverse problem of transformation discovery as found in signal processing, vision, inverse kinematics and many other natural tasks. According to this idea, a parallel search in the transformation space of a high dimensional problem can be decomposed into parts efficiently using the ordering property of superpositions. Deterministic formulations...
The current suite of spaceborne and in-situ assets, including those deployed by NASA, NOAA, and other groups, provides distributed sensing of the Earth's atmosphere, oceans, and land masses. As part of an activity supported through NASA's Earth Science Technology Office (ESTO), we have developed techniques that enable such assets to be dynamically combined to form sensor webs that can respond quickly...
