摘要：A method for matching obejcts based on spatial layout of regions based on a shape similarity model for detecting similarity between general 2D objects. The method uses the shape similarity model to determine if two obejcts are similar by logical region generation in which logical regions are automatically derived from information in the obejcts to be matched, region correspondence, in which a correspondence is established between the regions on the obejcts, pose computation in which the individual transforms relating corresponding regions are recovered, and pose verification in which the extent of spatial similarity is measured by projecting one document onto the other using the computed pose parameters. The method of the invention can be carried out in a microprocessor-based system capable of being programmed to carry out the method of the invention.
