Abstract

A real-time VME-bus preprocessor is presented for the extraction of a symbolic scene description from grey-level images. The hardwired pipeline processor consists of two stages. The first stage extracts the thinned greylevel contours using the local edge direction and a novel gradient maximum tracker which does not rely on thresholding. The second stage of the contour vectorizer breaks down the pixel-based contour image into a set of vectors describing the contours in terms of straight-line polygones.
