Embodiment 1

[0020] Such as figure 1 In the photo comparison device for multiple photos of one person shown, the photo reading module 1 is connected to the intermediate module 2, and the photo reading module 1 reads multiple photos of the person to be identified, and may include a scanner to scan the photos if necessary . The read photo data is transmitted to the middle module 2 to extract facial features and build a template.

[0021] The photo comparison device has a built-in photo module 3, in which there is a face database, which stores many face photos, and the photo module 3 extracts facial features from these face photos, and constructs templates respectively.

[0022] The data of the intermediate module 2 and the photo module 3 are all transmitted to the recognition module 4 for comparison and recognition, and then the result module 5 sorts and takes out candidate results for display on the display module 6 .

[0023] The comparison of the identification module 4 can adopt the me...

Embodiment 2

[0030] Such as figure 1 As shown in the device for comparing photos of one person with multiple photos, the comparison of the identification module 4 can adopt the method of seeking the maximum value of similarity, including a maximum similarity calculation unit.

[0031] All the other parts are the same as in Example 1

[0032] The working process of the device is as follows:

[0033] 1) The photo module contains existing M face photos, extract face features from these photos, and construct templates, each template in this module is marked as B i (0≤i≤M).

[0034] 2) The middle module extracts face features from N photos of the same person to be identified, and each feature template is marked as A j (0

[0035] 3) The recognition module compares the template in the middle module with the template in the photo module, and finds the maximum similarity with each template in the photo module, namely: S i =MAX(F(A j , B i )), where F is the comparison function of the t...

Abstract

The invention discloses a device for comparing a plurality of photos of the same user, and relates to an image identification and comparison technology. The device comprises a photo module, an intermediate module, an identification module and a result module. The photos of the same user are compared, so that the shortcoming of one-sidedness of comparison of only one photo can be effectively overcome, the influence of the quality of a certain photo is avoided, the matching rate of photo comparison is increased, and the device is convenient to use.

Description

technical field [0001] The invention relates to image recognition and comparison technology, in particular to a photo comparison device for multiple photos of one person. Background technique [0002] The face recognition photo comparison system uses face recognition technology to search and retrieve the identity of a specific person in a large number (thousands to millions) of databases (such as fugitive photo databases, missing persons photo databases, permanent population photo databases, etc.) . Support photo to photo, video stream to photo, video stream to video stream, etc. It can realize photo comparison and identity confirmation on LAN, intranet and Internet. [0003] The face recognition photo comparison system extracts the face information in the photos, compares the face information in the photos with the face information in the database of business personnel within a specified range, and then identifies the "similar" people in the photos the identity of a pers...
