| Abstract(in English) | The non-uniform quadtree, which divides a given quadrant into four unequal rectangles instead of equal squares, yield more compact region representations than quadtrees and it also decreases shift sensitivity of quadtree representations. However those non-uniform subdivisions endanger the nice properties of the quadtree representation, e.g., all neighbors of the given region are recognized by a simple tree traverse within a few steps. In this paper, we will introduce a graph grammar based on nPCE graph grammars. By spanning some additional links into a quadtree, the graph grammar can describe all adjacency relations within a given non-uniform quadtree. |
