The invention relates to the technical field of face recognition, in particular to a fractional modulation method, a face recognition method and a corresponding device. It aims to solve the problems that the current threshold setting is inconvenient and the recognition models in different fields cannot achieve the expected results when applied to other fields. For this reason, the score modulation method of the present invention constructs a score modulation model through a small amount of training data, and modulates the comparison scores of face images in different fields, so that the modulated scores are in the same distribution, and the face features in different fields Score compensation is performed on the comparison results, and the comparison of face features in different fields uses the compensated scores to keep the score distribution consistent, which is convenient for threshold setting during use and can achieve expected and stable error in face images in different fields. The alarm rate and pass rate indicators have improved the performance and user experience of face recognition technology in actual scenarios.
Description
technical field [0001] The present invention relates to the technical field of face recognition, in particular to a fractional modulation method, a face recognition method, a device, a medium and a terminal device. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. Face recognition has a wide application prospect in real life. For example, face recognition is required in security access control systems, public security criminal investigations, camera surveillance systems, network applications, identity recognition, and payment systems. [0003] The existing face recognition technology per...
