摘要:
After thinning an input image (drawing), a primitive is extracted. First, a rough primitive is extracted, and then the rough primitive becomes a primitive in a merge-split process according to a greedy strategy. Based on the primitive and the spatial correlation among primitives, an attribute graph describing the contents and the structure of the drawing is generated. The attribute graph is generated using a modified Delaunay triangle and an attribute set. An attribute graph having an attribute set is generated for each of an inquiry drawing and a comparison drawing which are compared with each other, thereby perform drawing comparison.

The present invention relates to three-dimensional model retrieval apparatus and method. The three-dimensional model retrieval apparatus according to the present invention comprises a model normalizing unit for rotating and/or translating a three-dimensional model so that main axis directions of the three-dimensional model are consistent with coordinate axes of a system coordinate system, and barycenter of the three-dimensional model is consistent with origin of the system coordinate system; a two-dimensional image generating unit for projecting said three-dimensional model respectively in a positive direction and a negative direction of each coordinate axis of said system coordinate system to generate a plurality of two-dimensional images; a model describing unit for generating a model descriptor of the three-dimensional model from said two-dimensional images; and a retrieving unit for retrieving, based on said model descriptor, a three-dimensional model which most matches an input query from a model database.

A query device part image and an assembly drawing image from a drawing database which is a search target are input. The assembly drawing image is classified into text and non-text areas in the layout analysis unit 10. In the device part extraction unit 11, part images are extracted from non-text areas. The device part comparison unit 12 collates the extracted part image and the query device part image.

According to an aspect of an embodiment, a method for searching a set of image data from a database which contains a plurality of sets of image data, at least one of the sets of the image data being associated with text data, the method comprising the steps of: obtaining keyword information; detecting first set of image data in said database associated with text data corresponding to said keyword information; and detecting second set of image data in said database on the basis of the feature of an image represented by said first set of image data.
摘要:
A method of assisting analysis of a production process assisting work for analyzing the relationship between quality factors and characteristic of a product and a program product and a recording medium for the same, comprising receiving a designation of a factor from a user at a computer, arranging images corresponding to said image data related to the received factor in a virtual space in a display device connected to the computer (S13), displaying the virtual space in which the images are arranged in the display device (S14), repeating the designation reception, arrangement, and display until the user judges that there is similarity between adjoining images in the displayed images, receiving designation of at least one image by the user from images having similarity between adjoining images (S15), automatically extracting common factors among factors of the designated image (S16), receiving a hypothesis of a relationship between the common factors designated by the user and quality of products, and verifying the relation hypothesis (S17) so as to thereby assist work for analyzing the relationship between factors selected by the user and the product characteristic and adding to factors feature quantity from the image data of products and feature quantity from text data relating to the process prepared by a production worker converted to numerals/characters (S11, S12).
