This paper introduces a measure for computing the dissimilarity between multiple polylines and a polygon based on the turning function, and describes a part-based retrieval system using that dissimilarity measure. This dissimilarity can be efficiently computed in time O(kmn log mn), where m denotes the number of vertices in the polygon, and n is the total number of vertices in the k polylines that are matched against the polygon. This dissimilarity measure identifies similarities even when a significant portion of one shape is different from the other, for example because the shape is articulated, or because of occlusion or distortion. The effectiveness of the dissimilarity measure in demonstrated in a part-based shape retrieval system. Quantitative experimental verification is performed with a known ground-truth, the MPEG-7 Core Experiment test set, in a comparison with the Curvature Scale Space method, and a global turning angle function method.
