This paper presents a method of extracting shape information from clipart images and then measuring the similarity between different clipart images using the extracted shape information. Previous methods of extracting shape information can be classified into outline-based methods and region-based methods. Included in the former category, the proposed method expresses the convex and concave aspects of an outline using the ratio of a rectangle. Experimental results demonstrated that the proposed method was superior in expressing shape information than previous outline-based feature methods.
