Embodiment

[0049] Seal specifications introduction, state-owned enterprises, state-owned joint-stock enterprises and other seals (including company seals, departmental seals) are all circular, with a diameter of 4.2cm, with a five-pointed star in the center, a star tip diameter of 1.4cm, and a round edge width of 0.12cm. The five-pointed star foreign journal unit name, circles from left to right, or the front part of the name circles from left to right, and the back part runs horizontally from left to right, that is, the name of the unit and department is placed horizontally under the star, and the printed text uses simplified Song typeface. Other images are similar.

[0050] PIL introduction, PIL (Python Image Library) is a third-party image processing library of python, but due to its powerful functions and large number of users, it has been considered as the official image processing library of python. Its official homepage is: PIL, http: / / pythonware.com / products / pil / .

Abstract

The invention discloses an image recognition method and device and a storage medium. The method relates to the technical field of image processing, and comprises the steps of carrying out the grayingprocessing, feature vectorization processing and sample set training of a normalized standard seal image, obtaining a trained sample set, carrying out the classification of the trained sample set according to a preset rule, and obtaining a classification recognition model; and enabling the classification and identification model to identify the normalized to-be-detected seal image, and calculatingthe matching degree of the standard seal image and the to-be-detected seal image by adopting a Match algorithm according to the color matrix. The technical scheme of the invention is provided for identifying the seal. The seals are with similarity, so the model can be conveniently trained, the trained model is high in recognition degree; experience data does not need to be obtained through a large number of experiments or through an expert system technology, time is saved, the technical scheme can replace manpower to identify the authenticity of the seal, the process speed of target image recognition is relatively high, the technology is simple, and the recognition accuracy is high.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image recognition method, device and storage medium. Background technique [0002] In some scenarios, it is necessary to identify the authenticity of seals (official seals, corporate seals, financial seals, etc.). For relevant personnel, it takes a lot of energy to identify a large number of seals, and the identification efficiency is low. [0003] Therefore, be badly in need of a kind of scheme that is convenient to distinguish the authenticity of seal at present, to save manpower, improve work efficiency. Contents of the invention [0004] In order to overcome the above problems or at least partially solve the above problems, embodiments of the present invention provide an image recognition method, device, and storage medium. [0005] Embodiments of the present invention are achieved like this: [0006] An image recognition method, comprising the steps o...
