ABSTRACT:
Images having a moving pattern against a fixed or quasi-fixed background are segmented by determining a silhouette of the moving pattern, and forming a segmentation image filling the silhouette. On a pixel-by-pixel basis, differences are determined between the current image and previous images of a sequence, and compared with a threshold to form a binary image of background and useful zone. The boundaries of the useful zone are regularized, and irregularities in the useful zone and in the background are suppressed. A segmentation image is then formed within the silhouette.
