Facial recognition machine all-in-one machineIt is based on the facial features of a person, first determining whether there is a face in the input facial image or video. If there is a face, it further provides information on the position, size, and location of each major facial organ. Based on this information, extract the identity features contained in each face, and then compare them with known faces to identify the identity of each person's face. So, what are the main functions of a facial recognition all-in-one machine?

1、 Facial capture and tracking function

Facial capture refers to detecting a portrait in a frame of an image or video, separating it from the background, and automatically saving it. And portrait tracking refers to the use of portrait capture technology to automatically track a specified portrait when it moves within the range captured by the camera.

2、 Comparison of integrated facial recognition machines

The integrated facial recognition machine is mainly divided into two comparison modes: verification mode and search mode. Verification mode refers to comparing the captured or specified portrait with a registered portrait in the database to verify whether it is the same person. The comparison of search modes refers to searching the database to see if all registered portraits have a specified portrait.

3、 Facial modeling and retrieval

At this point, the registered portrait data is modeled to extract facial features, and the generated facial feature file is saved in the database. When conducting facial search, model the specified portrait, then compare it with templates of all people in the database for recognition, and finally list more similar personnel based on the compared similarity values.

4、 Real person recognition function

The all-in-one facial recognition machine can recognize whether the person in front of the camera is a real person or a picture. This can prevent users from using fake photos, as this technology requires users to make facial expressions and coordinate actions.

5、 Image quality inspection

The quality of the image directly affects the recognition effect, and the image quality inspection function can evaluate the image quality of the photos to be compared and provide corresponding recommended values to assist in recognition.
