Problems solved by technology

[0007] But the shortcoming of the face recognition method in the prior art is, when the size of the face image database changes greatly, the existing face recognition identification features may no longer have enough identification information, and the recognition of the face recognition algorithm efficiency will be greatly reduced

Embodiment Construction

[0031] In the following, the application of the method in the banking system as an example will be described in conjunction with the accompanying drawings and specific implementation methods.

[0032] When a bank user withdraws money, the banking system sends a photo signal and a serial number that uniquely identifies the transaction to the transaction system through the network (TCP / IP). The camera sensor is installed in the groove of the cash machine (to facilitate the capture of the user's front complete face), take a photo every 20ms, and select the most complete face (with eyes and nose) through face recognition technology to save it for comparison with the faces stored in the system. Select the most complete image of the face through face recognition technology to save the completed method:

[0033] 1. First exclude images that do not capture faces.

[0034] 2. Next, choose a moderately sized, centered image as the best image.

[0035] The discrimination methods used a...

Abstract

A bank transaction image forensic acquiring method based on face recognition includes the procedures that: 1) the discrimination value is firstly initialized for preparing image acquisition: a camera on a bank client equipment starts to operate and corresponds to a serial number; 2) with the serial number, the camera snaps a group of face photos of the user; 3) the photo with the most complete face image is selected from the photos with the serial number to be stored; 3.1) the snapped photos without faces are removed; 3.2) the photo with proper size and face image in the center is selected as the optimum photo; 3.3) the optimum is stored for face recognition and corresponds to the serial number. Compared with prior art, the bank transaction image forensic acquiring method based on face recognition is simple and feasible, is used as the precondition method of the face recognition method, improves the recognition efficiency and accuracy and can be independently programmed into a function for being called by other programs.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a method for acquiring bank transaction forensics images based on face recognition. Background technique [0002] Face recognition is a kind of biometric recognition. First, the face image is collected, and then the collected face image is compared with the pre-stored face image to identify the identity of each face. From the perspective of application, face recognition includes two categories: 1) Identity recognition: identify the identity of the person based on the face image, and solve the problem of who is who, for example, in the public security system, the criminal's identity is detected from the database based on the criminal's photo. Identity; 2) Identity confirmation / verification: judging whether the face in the image is the designated person, that is, solving the problem of whether it is someone, such as the identity verification of the visitor in the ...
