[0046] 1. Summary of Feature Points

[0047] As mentioned in the content of the invention, the feature points are the core of this patent, and the size, position, and relative proportions of certain organs are unique and invariant in the face within a specific triangular area; while the proportions of other organs, although There are changes, but they can maintain relative stability. According to the change degree of the size, position and relative proportion of these organs, this patent divides them into three categories:

[0048] A) Unique invariant relationship:

[0049] distance between eyes;

[0050] The proportional relationship between the pupils of the eyes and the tip of the bridge of the nose

[0051] Nose bridge radian

[0052] Proportional relationship between the arc length of the bridge of the nose and the width of the nose

[0053] geometry of the cheekbones;

[0054] distance between eyebrows and upper lip;

[0055] the distance between the corners of the...

Abstract

The invention discloses an image automatic screening, query and identification system. The image automatic screening, query and identification system comprises an image input device, a database system, a storage system, a face detection system, a face registration system and a face comparison system. The image input device carries out the processes of real-time video inputting, video playback inputting and photograph batch importing. The database system stores personal associated portrait information including personal certificate information, a certificate photo, a life photo, a group photo and corresponding characteristic values. The storage system stores 3D-modeled portrait information namely the characteristic values and source indication. The face detection system reads an image input by the image input device, carries out face detection and collects a portrait according with modeling conditions. The face registration system carries out face modeling, the modeled face image is from the face detection system, and face modeling information is registered in the storage system. A face identification system carries out characteristic constant comparison retrieval on the portrait information, which is stored in the storage system, in the database system, thereby realizing person querying by persons and finding out the real identity of the person.

Description

technical field [0001] The invention relates to a computer-aided biological feature identification system, and more specifically relates to an image automatic screening query identification system. Background technique [0002] With the rapid development of the economy, the population density is further concentrated, especially with the severe anti-terrorism situation, we are facing various public security situations. At the same time, the rapid development of modern commerce, logistics and the Internet also imposes imminent requirements on the verification and confirmation of the identity of the other party. [0003] With the continuous development of science and technology, face recognition supported by a series of technologies such as cloud storage, cloud computing, and large database mining is undoubtedly the best way for remote identity confirmation. [0004] For remote face recognition, dynamic face recognition is undoubtedly the best and most reliable. However, limi...
