Face recognition method and device

Abstract

The embodiment of the invention provides a face recognition method and device. The face recognition method comprises the following steps: detecting whether a video streaming image contains the information of the local characteristics of a face, determining the face contained in the video streaming image according to a detection result, determining the face which is effectively recognized, and carrying out living body detection recognition; when the face which is effectively recognized meets a living body detection recognition condition, extracting a single frame of image or picture of the video streaming image, and generating an individual characteristic head portrait; according to the individual characteristic head portrait, extracting individual characteristic information; comparing a similarity between the individual characteristic information with sample plate characteristic information in an individual characteristic library; and starting a relevant application program when the similarity is greater than a preset similarity threshold value. Correspondingly, the embodiment of the invention also provides a face recognition device. According to the technical scheme provided by the embodiment of the invention, influence on a face recognition operation by external environment can be favorably eliminated, accuracy is higher when the identity of a user is judged through the face, and a recognition rate is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of face recognition, and in particular, to a face recognition method and 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. But under normal circumstances, face recognition only recognizes the facial information of the visible part of the face, and cannot obtain the facial information of other parts of the face, let alone integrate the facial information of the same face. [0003] At present, the application of face recognition technology is becoming more and more common. However, the face rec...

Problems solved by technology

But under normal circumstances, face recognition only recognizes the facial information of the visible part of the face, and cannot obtain the facial information of other parts of the face, let alone integrate the facial information of the same face.

[0003] At present, the application of face recognition technology is becoming more and more common. However, the face recognition technology in the prior art still has some technical defects, such as being greatly affected by the environment, easily deceived by photos, and not adapting to the natural changes of faces. Cause problems such as insufficient recognition rate

[0004] Therefore, a new method and device for face recognition are needed to solve the problem of poor recognition rate in the prior art
