Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] figure 1 It shows a schematic diagram of a device for similarly judging multiple images based on a digital signature according to one aspect of the present invention. Among them, the judgment device 1 includes but is not limited to a network host, a single network server, a set of multiple network servers, or a cloud composed of multiple servers. Here, the cloud may be composed of a large number of computers or network servers based on Cloud Computing, where cloud computing is a kind of distributed computing and a super virtual computer composed of a group of loosely coupled computer sets. Wherein, the judging device 1 includes a first acquiring device 11, a generating device 12, and a judging device 13.

[0023] The first acquiring device 11 acquires image feature information of an image. Specifically, the first obtaining device 11 obtains the image from...

Abstract

The present invention provides a device and method for similarity judgment of multiple images based on a digital signature, comprising: acquiring image feature information of an image; performing predetermined digital processing on the image feature information of the image to generate the image corresponding to the image a digital signature; wherein, the method further includes: according to the digital signature corresponding to each image in the multiple images to be processed, performing similarity judgment on the multiple images, and performing similarity judgment on the multiple images based on the similarity judgment result Treat accordingly. Compared with the prior art, the present invention performs similarity judgment based on the digital signature of each image in the plurality of images, and performs corresponding processing on the images according to the similarity judgment result, which improves the similarity judgment of multiple images. processing efficiency.

Description

Technical field [0001] The present invention relates to the field of Internet technology, and in particular, to an image processing technology for similarly judging multiple images through digital signatures. Background technique [0002] In applications such as search engines or information retrieval systems, a query sequence corresponds to multiple query results most of the time. In these query results, due to different hyperlinks, backlinks, or webpage sources, the same search information may be Two or more query results are presented to the user. Taking image as an example, when the user enters an image query sequence, the same image query result may have different versions, and each version corresponds to a different image query result. The situations that lead to different versions may include: image edge cropping The size is different, the logo added to the image is different, the noise in the image is different, or the image resolution is different. If these query resul...
