Embodiment 1

[0044] Such as figure 2 As shown, this preferred embodiment provides a similar image recognition system, which includes the following: an upload server 202 , an image database device 204 , an index server 206 , an image calculation server 208 , and an image retrieval front-end server 210 .

[0045] When building an image index database, user A uploads an image to be stored to the upload server 202 , the upload server 202 calculates the image signature of the image, and sends the image signature of the image to the image database device 204 . In this embodiment of the present application, images may also be captured from the network through a crawler system and then stored in the upload server 202, which is not limited in this application. Preferably, the upload server 202 uses the content information of the image itself (for example, the metadata of the image, such as color, texture, etc., rather than the byte stream) to calculate the image signature of the image, thereby gre...

Embodiment 2

[0063] based on figure 2 The identification system shown and image 3 with Figure 4 As shown in the identification device, this preferred embodiment also provides a method for identifying similar images, such as Figure 5 As shown, the identification method includes the following steps:

[0064] S502. Obtain an image signature corresponding to the content information of the input image; preferably, in figure 2 In the recognition system shown, the image retrieval front-end server 210 can obtain the content information of the input image input by user B, and send it to the image calculation server 208, and the image calculation server 208 can obtain the image signature corresponding to the content information of the input image . preferably, in image 3 In the identification device shown, the image signature corresponding to the content information of the input image is obtained by the obtaining unit 302 .

[0065] In this preferred embodiment, the image retrieval foregro...

Abstract

The invention provides a similar picture identification method and a similar picture identification device, which are used for acquiring image signatures corresponding to content information of input images, performing Hash operation to the image signatures, querying table items corresponding to results of the Hash operation in a pre-stored Hash table and identifying images similar to the input images in candidate images corresponding to queried table items. The similar picture identification method and the similar picture identification device solve the fault tolerance problem existing in a pattern identification technology and can accurately identify required similar images.

Description

technical field [0001] The present application relates to the technical field of multimedia image recognition, in particular, to a similar image recognition method and device. Background technique [0002] Similar image retrieval is a technology that has emerged in recent years and belongs to a type of multimedia recognition. It mainly includes main steps such as feature extraction, index construction, query, and similarity ranking. Such as figure 1 As shown, when building an image index database, user A uploads an image to be stored to the image server 10, and the image server 10 generates an image signature for the image, and uses the image signature as an index to facilitate subsequent retrieval queries. When it is necessary to identify similar images, user B requests similar image retrieval from the image server 10, and the image server 10 searches for similar images corresponding to the image index according to the image index. After the image server 10 finds an image...
