Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0063] Such as figure 1 As shown, a multi-modal image retrieval method based on design patents includes the following steps:

[0064] Step 1): Propose the image effective content extraction algorithm IECE (ImageEffectiveContentExtractionAlgorithm) to extract the effective content of the image, and dynamically select the grayscale stretching preprocessing operation on the image according to the range of the image histogram;

[0065] Definition 1: Effective content of an image: the image content that belongs to image information and is compared in patent examination.

[0066] Definition 2: Image-ind...

Abstract

The present invention relates to a multi-mode image retrieving method based on an appearance design patent. The method comprises the following steps: step 1): proposing a valid content extraction algorithm to extract valid content of an image, and performing a pre-processing operation on the image; step 2): extracting an image text feature; step 3): extracting an image fast local direction mode visual feature; and step 4): fusing the image text feature with the visual feature, and performing a multi-mode retrieval on the image. The present invention provides a multi-mode image retrieving algorithm with a text feature and a bottom-layer visual feature fused, which fully exerts the advantage of different mode features and improves retrieval accuracy; and the method is superior to the existing single-mode retrieving method and can well meet requirements of actual application.

Description

technical field [0001] The invention belongs to the technical field of image retrieval in design patents, and in particular relates to a multi-modal image retrieval method based on design patents. Background technique [0002] With the rapid development of my country's economy, design patents have become an important way to protect the intellectual property rights of enterprises, safeguard their own interests, and protect inventions and creations. Achieving quick search of design patents can help users obtain specified patent information and reduce imitation disputes on the one hand. On the other hand, it plays a very important role in realizing real modern management and enhancing the international competitiveness of enterprises. [0003] Different from complex and changeable images on the Internet, design patent images protect the texture and shape information of the image. Therefore, when extracting the underlying visual features of the image, the texture and shape featur...
