摘要： The present invention discloses a shape comparison apparatus and method based on contour decomposition and correspondence. The apparatus comprises a polygonal approximation unit for approximating an image object contour as a polygon, namely representing the image object contour into an ordered contour primitive sequence; an attribute generation unit for calculating attribute value for contour primitive and contour primitive composition; and a comparison unit for establishing correspondence of polygons and hence calculating similarity between contours. Preferably, the apparatus further comprises an image object contour extraction unit for extracting, in the case the input into the apparatus is an image object rather than an image object contour, an image object contour of an image object inputted into the apparatus.

摘要： A data retrieving part searches a database for data under the conditions for a search input by a user through a search condition input part. A classifying and arranging part classifies and arranges data (search results) using feature values. A ground information providing part provides each data with ground information visualizing the ground for classification and arrangement of the data. The ground information is, for example, visualized distribution information of feature values of the data, color histogram label information, and label information on wavelet conversion feature values. A display part displays each data together with corresponding ground information, in accordance with the information on classification and arrangement from the classifying and arranging part.
