Embodiment Construction

[0036] specific implementation

[0037] The gist of the present invention is to design a retrieval method for design patents based on image content analysis, so as to solve the problems of time-consuming and unsatisfactory retrieval results existing in the current retrieval of design patents. The implementation details and effects of the present invention will be described below in conjunction with the flow chart and examples of the present invention in the accompanying drawings, so as to further explain the technical features and advantages of the present invention.

[0038] The implementation steps of the present invention include image database registration and user retrieval two major parts (as attached figure 1 Show).

[0039] 1) Design patent image library registration

[0040] Purpose: To express images with less data than the original image data, and to form a database of image features for design patents.

[0041]Step 1: Perform the following image preprocessing on...

Abstract

The invention discloses a design patent retrieval method based on the analysis of an image content, which comprises the following steps: extracting a profile of a target area and distance between the profile and an external rectangular thereof to be as an form feature; adopting a quadtree form to partition a target image; taking the ratio of a target pixel number of the block area to be as a structural feature, when retrieving, utilizing the kinds of the two features to weight, and calculate and the similarity of a query image and an image in the database; and sorting and returning the image of the retrieval result according to the similarity. The invention adopts a background removal method based on priori knowledge, adopts the profile of the target and the distance between the external rectangular thereof to be as the form feature, and adopts the ratio of the target pixel ratios in the quadtree decomposition blocks to be as the structural feature. The invention can effectively solvethe problem that the existing design patent retrieval method has long retrieval time and low efficiency, can not analyze the content of the image, and can greatly improve the effect of the design patent image retrieval.

Description

technical field [0001] The invention relates to an image retrieval technology, which belongs to the fields of multimedia retrieval, computer vision, image processing, pattern recognition, etc., and in particular relates to a retrieval method for design patents based on image content analysis. Background technique [0002] With the in-depth development of economic globalization and the vigorous rise of knowledge economy, the level of patent development has become a strategic symbol to measure a region's comprehensive strength, development ability and core competitiveness. Design patents have always been known as "small patents, big markets", which play a pivotal role in market competition and are an important factor in enhancing the competitiveness of enterprises. From the perspective of developed countries, whether it is applying for patents, implementing patents, or using intellectual property strategies to compete, enterprises and industries are the most active subjects. ...
