Method and device for obtaining an output in skeleton form that is a simplified representation of an image with pixels joined together. The pixel image is converted into a contour listing that consists of one or more series of two-dimensional contour points. The contour listing is supplemented so that the distance between two successive contour points is half a pixel width. The contour listing is then repeatedly stripped until the output in skeleton form remains. Zero, one, two or three points in the new contour listing are generated at each contour point, the points with zero or half a pixel width are shifted in the X direction and/or the Y direction towards the inside of the image described by the contour listing. <IMAGE> |
