Fast orthogonal search, IR images, multiple hot-spot target.
The intensity pattern of a long-range, or small
extended, infrared (IR) image target can be accurately
modeled as a bivariate Gaussian (BG) function. In
target tracking application using the IR images, the
parameters of the target intensity profile are estimated
in order to track the target. In this paper, the two
dimensional fast orthogonal search (2D-FOS) is
introduced as a method to model the intensity pattern of
the small-extended IR target. We demonstrate that 2D
FOS can accurately model the BG target intensity
profile in the cases of (i) very low signal-to-noise S/N
ratio, (ii) multiple hot-spot target, and (iii) targets
located at the edges, or the corners, of the image.
