Abstract

A method is presented where the foreground is enhanced by an relative focus-map estimation. In the case of moving patterns a Stauffer Grimson approach is used to suppress background. In case of small and subpixel target size statistical evaluation is used for a rough classification. A new solution is given by a combination of foreground separation, relative focus-map generation and histogram-based local evaluation to find the foreground objects.
