ABSTRACT:
A hierarchical object encoding technique or process capable of representing general binary arbitrary shapes that include, for example, embedded or disconnected components. The method decomposes successive layers of general binary arbitrary shapes into simple arbitrary shapes. Each mask formed in this manner is a simple arbitrary shape having only a continuous outer boundary. Accordingly, each outer boundary is encoded, preferably by a contour encoding method, to provide accurate encoding of general binary shapes.
