Face quality in-vivo joint detection device and method, computer equipment and medium

The invention relates to the technical field of computer vision, and provides a human face quality in-vivo joint detection device and method, computer equipment and a medium, and the device comprises a quality in-vivo joint detection model which carries out the human face detection of a human face image through a multi-task quality in-vivo joint detection model, can carry out the quality detection and in-vivo detection at the same time, and improves the detection precision. And the operation speed of detection is improved. Moreover, the quality in-vivo joint detection model can make full use of the correlation between the two features to improve the expression ability of the neural network, and especially, the in-vivo detection module is connected with the feature extraction module and the quality detection module, and is used for extracting in-vivo features according to the face features, and obtaining in-vivo detection results according to the quality features and the in-vivo features. The correlation betwe
