Multiple objects detection and tracking in passive scanning millimeter-wave imaging systems

This paper describes algorithms for detection and evaluation of trajectory parameters of small, spatially moving objects by passive optical and radio thermal vision system. The algorithms are based on spatial and temporal image processing. During spatial processing, a system of equations representing a sufficient condition for the conjugation of direction vectors to objects in stereo pairs is solved. During temporal processing vectors of the directions on accessory to objects in a sequence of the periods of supervision are distributed. The results of the algorithms theoretical and experimental examination are given. They are showing the advantage of the joint application of the two approaches.
