Example Embodiment

[0019] Example one

[0020] Such as figure 1 As shown in the photo comparison device for one person with multiple photos, the photo reading module 1 is connected to the middle module 2, and the photo reading module 1 reads multiple photos of the person who needs to be identified, and can 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 construct a template.

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

[0022] The data of the middle module 2 and the photo module 3 are transmitted to the identification module 4 for comparison and identification, and then the result module 5 sorts and extracts candidate results for display on the display module 6.

[0023] The comparison of the recognition module 4 may adopt a method of...

Example Embodiment

[0029] Example two

[0030] Such as figure 1 In the photo comparison device with multiple photos of one person shown, the comparison of the recognition module 4 can adopt a method of finding the maximum similarity, including a maximum similarity calculation unit.

[0031] The rest is the same as the first embodiment

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

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

[0034] 2) The intermediate module extracts facial features for N photos of the same person to be recognized, and each feature template is denoted as A j (0

[0035] 3) The recognition module compares the template in the intermediate 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 two te...

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...
