Scientific paper

Presented in this paper are the designs of several algorithms which enable the identification and tracking of various regions within a series of images using FPGA technology. Two example probLem domains in the areas of plasma physics and observational astronomy have been expolored. In the plasma physics application, an initial pixel extraction technique has been expanded to include spatial (related to the distance from a cathode) and value measurements (based on intensity values), which are subsequently merged in order to identify different intensity / emissivity regions within a plasma assisted deposition system. The optimum combination of these and other techniques are discussed, together with their reasons for selection. The control signals, decoding method and subsequent processing steps, associated with how a point within individual images is selected, will also be presented. In the astronomical application, a variation of a scene change detection mechanism is shown and how this system was adapted in order to track and chart the motion of Near-Earth Objects (NEOs).
