Embodiment Construction
[0043] The purpose of the present invention is to overcome the shortcomings of the prior art and the shortage of training samples, and propose a three-dimensional face recognition method based on Bayesian multivariate distribution feature extraction, so that it has a better recognition effect under single-sample training conditions.
[0044] In the following description, the present invention will be further explained in detail in conjunction with the accompanying drawings and specific implementation methods.
[0045] refer to figure 1 As shown, the 3D face recognition method based on Bayesian multivariate distribution feature extraction includes three parts: 3D data preprocessing, feature extraction and recognition classification.
[0046] Step 1, 3D data preprocessing: such as figure 2 As shown, the preprocessing process of 3D face data is shown. Specific steps are as follows.
[0047] Step 11: Valid data collection. The deficiencies of 3D data include missing data, pea...
