Problems solved by technology

However, this authentication and counterfeiting system needs to shoot microscopic images, and the pixel requirements are 15-60 million pixels, which cannot well meet the public's needs for artwork identification. The speed is slow and consumes a lot of CPU / GPU computing resources and memory resources

Embodiment Construction

[0042] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Such as figure 1 As shown, the image search method for artwork identification provided by the present invention includes the following steps: first, when the user inputs a search image to perform a search request, search for highly matching historical images in the experience database, if the search If it is found, the search results and similarity corresponding to the highly matched historical pictures will be displayed to the user. Otherwise, use the Hash algorithm to grayscale process the retrieval image to obtain the information fingerprint, and perform rough matching in the gallery according to the information fingerprint to obtain the first result set. Afterwards, for the pictures in the first result set, according to the stable feature points and sub-picture feature points of the search graph, the SIFT ...

Abstract

The invention discloses an artwork identification method for searching for pictures by using a picture. The method comprises the following steps that S1, when a user inputs a search picture to conducta picture searching request, highly-matched historical pictures are searched for from an experience library, and if the pictures are searched for, search results corresponding to the highly-matched historical pictures and similarities are displayed to the user, otherwise, the second step is started; S2, a Hash algorithm is adopted for conducting gray processing on the search picture to obtain aninformation fingerprint, and rough matching is conducted according to the information fingerprint in a picture library to obtain a first result set; S3, for pictures in the first result set, accordingto stable feature points and sub-picture feature points of the search picture, an SIFT algorithm is adopted for quick matching to obtain a second result set; S4, the SIFT algorithm is adopted for precisely matching pictures in the second result set to obtain final similar pictures, and the pictures are ranked according to the similarities. By means of the method, through rough matching, quick matching and fine matching, on the basis of ensuring the matching precision, the search efficiency is improved.

Description

technical field [0001] The invention relates to a method for searching images by images, in particular to a method for searching images by images for artwork identification, and belongs to the technical field of anti-counterfeit identification. Background technique [0002] With the rapid development of my country's economy and cultural background, the appreciation, trading and collection of artworks have gradually become the life pursuit of some people. However, due to the unbalanced development of the field of artworks in our country, fake and inferior artworks are rampant, plagiarism and imitation are commonplace, and false propaganda and fraud occur from time to time. [0003] For this reason, it is very necessary to identify artworks in the process of circulation. Existing works of art identification are generally author verification and experience verification. Author verification is the author's own verification of his own work. However, author verification will ha...
