Embodiment 1

[0025] Such as figure 1 Shown, the authenticity identification method of the seal of the present invention comprises the following steps:

[0026] a. Establish a database and input various standard image information of seals;

[0027] b. Obtain the on-site seal image information;

[0028] c. Preliminarily compare the image information of the on-site seal with the standard image information of the seal, if they are not the same, skip to step f, and if they are the same, execute step d;

[0029] d. Perform background processing on the on-site seal image information and the standard image information of the seal, and compare them separately after cutting out the images. If they are not the same, go to step f, and if they are the same, execute step e;

[0030] e. Overlap and compare the image information of the on-site seal with the standard image information of the seal, if they are not the same, then jump to step f, and if they are the same, then identify the seal as true;

...

Embodiment 2

[0034] On the basis of the above-described embodiments, in order to further better implement the present invention, in the step a, when entering various standard image information of the seal, the image information of the authentic seal is scanned by a high-definition scanner or taken by a high-definition camera device, and saved in the database. In order to reduce the errors caused by shooting and scanning, as a preferred method, in the step b, when acquiring the image information of the on-site seal, a high-definition scanner or high-definition camera equipment when recording the standard image information of the seal is used.

Embodiment 3

[0036] On the basis of the foregoing embodiments, in order to further better implement the present invention, in the described step c, when the image information of the on-site seal and the standard image information of the seal are initially compared, the image of the on-site seal and the standard image of the seal are placed on the same interface , and the size is scaled to be consistent for observation and comparison. Multiple groups of comparison can be set in the interface, and each group focuses on a parameter or an orientation of the highlighted image, so that comparison and identification can be conveniently carried out.

Abstract

The invention relates to the field of image comparison, in particular to a seal authenticity identification method which is mainly applied to art work identification and is simple and high in identification accuracy. The seal authenticity identification method comprises the following steps: firstly, establishing a database, and inputting standard image information of various seals; then acquiringfield seal image information, preliminarily comparing the field seal image information with the seal standard image information, and if the field seal image information is obviously different from theseal standard image information, identifying that the seal is false; if no obvious difference can be seen, independently comparing the field seal image information with the seal standard image information, removing other interference factors, and if the field seal image information is different from the seal standard image information, identifying that the field seal image information is false; and if the image information is still quite similar to the standard image information, performing overlapping comparison on the field seal image information and the standard seal image information, andperforming final identification to obtain a true and false identification result. The method has the characteristics of simplicity, high identification efficiency and high identification accuracy.

Description

technical field [0001] The invention relates to the field of image comparison, in particular to a seal authenticity identification method with simple method and high identification accuracy, which is mainly used in the identification of artistic works. Background technique [0002] Stamps, also known as stamps, are used as stationery printed on documents to indicate identification or signature. Generally, stamps are first stained with pigments and then printed. Those that do not stain with pigments and are printed on a flat surface will appear concave and convex are called steel seals. Some are stamps. A wax seal on wax or wax, on an envelope. The production materials are metal, wood, stone, jade and so on. In the antique calligraphy and painting industry, the identification of seals is one of the important identification means. Once the identification is wrong, it will cause great losses. The existing identification methods mainly rely on manual work, and generally authori...
