Embodiment Construction

[0016] Such as figure 1 Shown, the present invention comprises the following steps:

[0017] Step 1. Build a database in the system; a photo archive module and a photo comparison module are arranged in the database; data transmission can be carried out between the photo comparison module and the photo archive module;

[0018] Step 2. When the relevant personnel log in to the system for the first time, the system will take a photo of the relevant personnel, and this photo will be automatically uploaded to the photo archive module as a reference photo;

[0019] Step 3. The relevant person starts the process of multiple logins. At each login, the system will first recognize the face of the relevant person, and compare the recognized image with the reference photo in step 2. If the similarity reaches the specified value, The relevant personnel log into the system, and the recognized image is stored in the photo comparison module; if the similarity does not reach the specified val...

Abstract

The present invention discloses a method for automatically replacing a reference photograph according to similarity concentration ratios. The method includes the following steps that: (1) a database is constructed in a system, a photograph archiving module, a photograph comparison module and a photograph replacement module are set in the database; (2) when a relevant person logins the system for the first time, the system takes a picture of the relevant person, wherein the picture is adopted as a reference photograph; (3) when the relevant person starts a process of multiple times of login; when the relevant person logins the system each time, the system identifies the face of the relevant person, an identified image is compared with the reference photograph, if the similarity of the identified image and the reference photograph reaches a specified value, the relevant person logins and enter the system; and (4) when the number of successful logins of the relevant person in the step 3 reaches a specified value of the system, images stored in the photograph comparison module are automatically compared, and a photograph with the highest similarity concentration ratio in all the images is identified and is adopted as a new reference photograph. With the method of the invention adopted, face recognition can be carried out more quickly, more accurately and conveniently.

Description

technical field [0001] The invention relates to face recognition technology, in particular to a method for automatically replacing a reference photo according to similar concentration. Background technique [0002] The traditional face recognition technology is based on human facial features. For the input face image or video stream: first judge whether there is a face, if there is a face, then further give the position, size and location of each face. Location information for each major facial organ. Based on this information, the identity features contained in each face are further extracted, and compared with known faces, so as to identify the identity of each face. [0003] The traditional face recognition technology is to compare the recognized face with the known face saved by the system. If the saved face is different, there may be a risk that the face cannot be recognized, and I need to find the relevant person to take the latest photo. Contents of the invention ...
