[0077] Example two
[0078] Figure 2a A schematic flow chart of a method for detecting key points of a face provided by the second embodiment of the present invention is given. This embodiment is optimized on the basis of the above-mentioned embodiment. In this embodiment, the person in the current frame to be tested will be obtained. The posture correction information of the face in the original face image is further optimized as follows: the face posture information of the original face image in the frame before the current frame to be tested is obtained as the face original image of the current frame to be tested The posture of the face corrects the information.
[0079] At the same time, this embodiment will correct the face posture in the original face image according to the posture correction information to obtain a face correction image. The specific optimization is: the original face image and the posture correction information As input data, the image alignment model is ...
