Meituan publicly "training method for living detection models" patent

The science and technology corner material informed Meituan related company Beijing San Kuai Online Technology Co., Ltd. recently released the patent of "a training method for a living detection model", which belongs to the field of artificial intelligence technology.Application number: CN202210377207.5.

The Sky Eye Increasing APP shows that the method of this patent includes: the facial image samples are fused with the corresponding living clues and attack clue feature maps, respectively to obtain the living clues and attack clues corresponding to the face image sample; based on people -based peopleThe live body clue diagram and attack clue diagram corresponding to the facial image sample are trained to train the initial live detection model to obtain a living detection model.

The publicity incorporates the extraordinary clues and attack clue feature maps to the original map, so that the living body and attack characteristics of the face image sample of the face are enhanced, and then the face image sample training model based on the clue enhanced person's face image sample is improved to improve the living body detection model to improveThe accuracy of the trained live detection model can capture the local characteristics of the face image when using the live detection model for detection, thereby obtaining a better detection effect.
