    • A design support apparatus extracts feature data corresponding to design data to be searched upon receiving the design data to be searched. The apparatus checks the extracted feature data against the feature data associated with the feature associated information, ordering the design data associated with the feature associated information in descending order of similarity to the design data to be searched, retrieving one piece of the ordered design data. The apparatus generates a classification hierarchy consisting of pieces of classification data obtained by classifying a set of the retrieved design data based on a degree of feature similarity using the feature data associated with the feature associated information. The apparatus selects the design information closely associated with the classification data by fetching the design information corresponding to the design data contained in the classification data from the design associated information associating the design data and the design information.
    • 设计支持装置在接收到要搜索的设计数据时,提取与要搜索的设计数据相对应的特征数据。 该装置根据与特征相关信息相关联的特征数据来检查提取的特征数据,以与要搜索的设计数据相似的顺序排列与特征相关信息相关联的设计数据,检索一条有序设计数据。 该装置生成分类层次,其由通过使用与特征相关信息相关联的特征数据,基于特征相似度的程度来分​​类检索到的设计数据而获得的分类数据组成。 该设备通过从与设计数据相关联的设计关联信息和设计信息中提取与包含在分类数据中的设计数据相对应的设计信息来选择与分类数据密切相关的设计信息。

    • 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.
    • 本发明公开了一种基于轮廓分解和对应关系的形状比较装置和方法。 该装置包括用于将图像对象轮廓近似为多边形的多边形近似单元,即将图像对象轮廓表示为有序轮廓图元序列; 用于计算轮廓原语和轮廓图元组合的属性值的属性生成单元; 以及用于建立多边形的对应关系并因此计算轮廓之间的相似性的比较单元。 优选地,该装置还包括图像对象轮廓提取单元,用于在输入到装置中的图像对象而不是图像对象轮廓的情况下提取输入到装置中的图像对象的图像对象轮廓。
