  • Publication number: 20240282149
    Abstract: Disclosed in the present application are a liveness detection method and apparatus, a training method and apparatus for a liveness detection system, and an electronic device and a storage medium. The liveness detection method comprises: acquiring two target images, which are obtained by means of a first sensor and a second sensor respectively performing collection on the same face to be recognized; extracting target depth information from the two target images by using a deep generative network; and performing detection on the target depth information by using a liveness detection model, so as to obtain a liveness detection result of said face.

  • Publication number: 20240273879
    Abstract: The present application provides a model training method. In a model training phase, based on a first reference bounding box and its corresponding real bounding box and real category, a model to be trained is prompted to continuously learn a bounding box distribution and identifying a category of a target object; and determine a loss value based on a determination result set output by a determination sub-model, and then continuously update model parameters for multiple rounds of iterations based on the loss value.

  • Publication number: 20240249559
    Abstract: Embodiments of the disclosure provide an image liveness detection method and device. The method includes: performing semantic segmentation processing on a to-be-detected image to obtain a first masked image corresponding to a medium image block in the to-be-detected image; performing a biometric recognition on the to-be-detected image to obtain boundary information of a biometric image block in the to-be-detected image; performing pixel processing on the to-be-detected image based on the boundary information to obtain a second masked image corresponding to the biometric image block; obtaining, through calculation, a degree of overlap between the medium image block and the biometric image block based on the first masked image and the second masked image; determining a liveness detection result of the to-be-detected image according to the degree of overlap.

  • Publication number: 20240135643
    Abstract: The embodiment of the present application provides an information processing method, a device, a computer device, and a storage medium. The embodiment of the present application obtains a target video, each frame of the target video including a face image corresponding to a same object; inputting the face image of each frame into a first target preset backbone model, and outputting a first target image feature; inputting the first target image feature into a first target preset network model, and correspondingly outputting a first target expression coefficients. By decoupling the first target expression coefficient from non-expression coefficient, an accuracy of the expression coefficient that is extracted is greatly improved.

  • Publication number: 20240135747
    Abstract: An information processing method is provided. The method includes obtaining a target video. A first target image feature corresponding to a face image of each frame is obtained. A target identity coefficient and a target texture coefficient corresponding to the target image feature in the face image of a different frame in the target video are obtained. A first target identity feature is obtained according to the target identity coefficient, and a first target texture feature is obtained according to the target texture coefficient. Once a first target feature is obtained by splicing the target image feature, the first target identity feature and the first target texture feature, a first target expression coefficient is obtained based on the first target feature.
