Embodiment example
[0080] Taking a large-scale human face image database as an example, the implementation process of this method will be described below. The face image library in this example contains 2000 Chinese faces, each with three images of -30°, 0° and 30°. Figure 5 Three images of the same person are shown. Our 3D deformable face model comes from the 3D face data of 60 Chinese people. These data are obtained by optical synthesis of photos taken by two cameras. After preprocessing and registration, each face data contains 26498 vertices. In the end, we took 9 shape feature vectors, and manually calibrated 60 feature points on the model, such as figure 2shown. The implementation process is as follows:
[0081] 1. Training stage:
[0082] A) LDA gesture recognition base:
[0083] We divide the poses into three intervals of -30°, 0° and 30°, and use 200 face sub-images detected by the Adaboost method for each type of pose as a sample training base for LDA pose recognition. The out...
