[0103] The present invention will be further described below in conjunction with the drawings and embodiments.
[0104] Please refer to figure 1 , The present invention provides a single image face pose estimation method based on depth value, which is characterized in that it comprises the following steps:
[0105] Step S1: Obtain a face image of the pose to be estimated;
[0106] Step S2: preprocessing, converting the face image to be estimated into a grayscale image, normalizing the grayscale value to [0,1], and performing denoising and normalization processing, and converting the processed grayscale image The size is unified to 64×64;
[0107] Step S3: For the preprocessed grayscale image, the affine transformation invariance initialization principle (ATIIA) is introduced to establish an initial model, the traditional active shape model (ASM) method is improved, and the two-dimensional values of ten facial feature points are extracted. The ten facial feature points are the lef...
