Abstract: A method and device for updating data, an electronic device and a storage medium are provided. The method includes that: a first image of a target object is acquired, and a first image feature of the first image is acquired; a second image feature is acquired from a local face database; similarity comparison is performed between the first image feature and the second image feature to obtain a comparison result; responsive to that the comparison result is greater than a feature update threshold, a difference feature between the first image feature and the second image feature is acquired, and the difference feature is taken as a dynamic update feature; and the second image feature is adaptively updated according to the dynamic update feature to obtain updated feature data of the target object.

Abstract: An ambient light parameter is acquired by detecting ambient light of a surveillance area. When there is a target object in the surveillance area, a movement distance of the target object is detected. When the ambient light parameter meets an ambient light condition and the movement distance of the target object is no less than a distance threshold, the ambient light parameter is changed by adjusting screen brightness of a display device according to the ambient light parameter. A face image of the target object after the ambient light parameter has been changed is acquired. A comparison result of comparing the face image to a preset image is acquired. A face recognition result is acquired according to the comparison result.

Abstract: Provided are a method and device for detecting a living-body, and a storage medium. The method includes that: a first image captured by a first camera is acquired, and face detection processing is performed on the first image; a second image captured by a second camera is acquired responsive to detecting that the first image includes a face, where the first camera and the second camera are different types of cameras; and face detection processing is performed on the second image, and responsive to detecting that the second image includes a face, a living-body detection result is obtained based on a matching result of the face detected in the first image and the face detected in the second image.

Abstract: Embodiments herein disclose a method and device for processing an image, electronic equipment, and a storage medium. The method is as follows. A face image frame sequence of which a first face parameter meets a preset condition is acquired by filtering an image frame sequence. A second face parameter of each face image in the face image frame sequence is determined. A quality score of the each face image in the face image frame sequence is determined according to the first face parameter and the second face parameter of the each face image in the face image frame sequence. A target face image for face recognition is acquired according to the quality score of the each face image in the face image frame sequence.

Abstract: Provided are an access control method and device, and a storage medium. The method includes that: a collected image to be recognized is recognized to obtain a recognition result, where the image to be recognized includes a present graphic code; in condition that the recognition result indicates that the present graphic code is a target graphic code, the present graphic code is parsed to obtain user information and generation time contained in the present graphic code; and an access control device is controlled to be opened according to the user information and generation time in the present graphic code.

Abstract: An identity verification method and device and a storage medium are provided. The method includes that: a face image of an object to be verified is acquired; responsive to the condition that the face image is included in a predetermined face image library, a target verification mode for the object to be verified is acquired; and the object to be verified is verified according to the target verification mode to obtain a verification result.

Abstract: An attendance management system includes: a cloud data platform, the cloud data platform storing registration information of an object subjected to an attendance check and an attendance record of the object, and the registration information comprising identity information and attribute information; at least one attendance terminal, each of the at least one attendance terminal exchanging data with the cloud data platform by means of a predetermined interface, and each attendance terminal being used to receive, by means of the predetermined interface, the registration information of the object transmitted by the cloud data platform; and an acquired facial image of the object. The attendance record includes at least one of the acquired facial image of the object, an attendance time, and an attendance region.
