After thinning an input image (drawing), a primitive is extracted. First, a rough primitive is extracted, and then the rough primitive becomes a primitive in a merge-split process according to a greedy strategy. Based on the primitive and the spatial correlation among primitives, an attribute graph describing the contents and the structure of the drawing is generated. The attribute graph is generated using a modified Delaunay triangle and an attribute set. An attribute graph having an attribute set is generated for each of an inquiry drawing and a comparison drawing which are compared with each other, thereby perform drawing comparison.
