A method of visual tracking with use of color includes the step of
three-dimensional color modeling of the target, the step of target
recognition for initially perceiving the target, and the step of visual
tracking for repetitive visual tracking. In order to be robust to
irregular or abrupt changes of illumination, the present invention
provides a visual tracking method in which characteristics of the
photographing element (CCD or CMOS) used by the camera are analyzed
beforehand and the results of the analysis are modeled by a B-spline
curve, allowing effects of the real-time visual tracking and adaptability
to situations of rapid target movement.
