Anti-counterfeiting bill authentic identification system and method based on multispectral images

Abstract

The invention belongs to the technical field of financial security authentic identification and identification, and discloses an anti-counterfeiting bill authentic identification system and method based on multispectral image. The method comprises the steps: carrying out the image collection of an anti-counterfeiting bill through an image collection module, and obtaining anti-counterfeiting bill images under different spectrums; preprocessing the acquired bill images, wherein preprocessing includes color compensation, geometric correction, filtering and noise reduction; extracting anti-counterfeiting features from the infrared and ultraviolet images, and fusing multiple features to judge the authenticity of the anti-counterfeiting bill; and detecting a text area on the white light image, and recognizing bill face text information, wherein the bill face text information comprises bill types, affiliated organizations, bill numbers, accounts and money amounts. According to the invention,bill authentic identification is carried out by using a multi-mode multi-feature fusion mode, so that the authentic identification accuracy and reliability are improved; and the detail information ofthe anti-counterfeiting mark can be captured, and accurate matching of the feature points is achieved. Moreover, the matching speed is high, and the requirement of real-time performance of online detection can be met.

Description

technical field [0001] The invention belongs to the technical field of counterfeit identification and identification for public security, and in particular relates to a multi-spectral image-based anti-counterfeit bill identification system and method. Background technique [0002] Currently, the closest prior art: [0003] Anti-counterfeiting bills refer to various securities and certificates with anti-counterfeiting marks or features, including checks, bills of exchange, certificates of deposit, stocks, corporate bonds, invoices, tickets, etc. Anti-counterfeit bills are one of the important certificates in the circulation process of the national financial market, and undertake the capital circulation business among social entities such as individuals, enterprises, and banks.

What followed was an increase in illegal cases caused by counterfeiting bills, which seriou...

AI Technical Summary

Problems solved by technology

[0009](1) The existing technology utilizes a single type of anti-counterfeiting features, resulting in poor accuracy and reliability of counterfeiting

[0010](2) The existing technology uses the global information of anti-counterfeiting features, but does not use its detailed information when matching, resulting in slow matching speed and poor real-time online detection

[0011](3) The existing technology does not fully recognize the face information, and the recognition accuracy is poor

[0012](4) The existing technology does not establish a bill database, which is not convenient for the unified management of anti-counterfeiting bill data

[0013] Due to the imperfection of image acquisition technology, the types of anti-counterfeiting features are limited; due to the variety of bills and face information, the difficulty of identification is increased
