摘要: In content based image retrieval, systems allow users to ask for objects similar in shape a query object. However, there is no clear understanding of how computational similarity corresponds human similarity. this paper several measures were evaluated on planar, connected, non-occluded binary shapes. Shape using algebraic moments, spline curve distances, cumulative turning angle, signal curvature and Hausdorff- distance compared judgments twenty test shapes against large database.
