AI Technical Summary
Technical Problem
In the prior art, the image differences caused by factors such as camera position, angle, and light conditions in facial recognition lead to a decrease in the detection accuracy of target persons.
Method used
A variety of authentication methods are adopted, including identity authentication based on appearance features and identity authentication based on dynamic features (such as gait recognition). By detecting the static and dynamic attributes of the characters in the video, selecting appropriate authentication methods to improve detection accuracy.
Benefits of technology
It effectively suppresses the reduction in the detection accuracy of target characters due to image differences, and improves the overall performance of the face recognition system.

Abstract
To suppress a decrease in the accuracy of detecting a target person due to the difference in videos.SOLUTION: The present invention comprises: a selection unit for detecting a person showing up in a moving-image video and selecting an authentication scheme in accordance with the manner of how the detected person shows up; and an authentication unit having a first authentication scheme for re-identifying the appearance attribute of a person and thereby authenticating whether or not the detected person is a first person, and a second authentication scheme for re-identifying the dynamic attribute of a person and thereby authenticating whether or not the detected person is the first person, the authentication unit thus authenticating the detected person by the authentication scheme selected by the selection unit.SELECTED DRAWING: Figure 7
