Claim 14:
15. The computing device according to claim 14, wherein the extracting a feature map from the difference image by using a pre-trained face living body detection model, and decoupling the object reflectivity corresponding to the target detection object and the object normal vector corresponding to the target detection object from the feature map; and determining, by using the face living body detection model, whether the target detection object is a living body according to the object reflectivity and the object normal vector comprises:
inputting the difference image into the face living body detection model, obtaining the feature map by extracting an image feature by using a convolution layer in the face living body detection model, decoupling the object reflectivity corresponding to the target detection object and the object normal vector corresponding to the target detection object from the feature map, and determining, by using a global pooling layer and a fully connected classification layer in the face living body detection model, whether the target detection object is a living body according to the object reflectivity and the object normal vector.
