[0017] The specific embodiments of the present invention will be described in further detail below.
[0018] like figure 1 As shown, the steps of the LDA subspace learning method applied to the improved metric post-processing of face recognition according to the present invention are as follows: first, take a photo of a digital camera, a camera, etc., to obtain a face image as a research object, and then sequentially perform the face image Preprocessing, extracting GMLPQ feature set, Adaboost selector, LDA subspace analyzer, and finally performing face feature comparison.
[0019] Attached to the following figure 1 The schematic diagram of the algorithm shown is a detailed description of the specific implementation of the method.
[0020] ①Preprocess the face image, such as normalizing, filtering, and specifying resolution.
[0021] ② Calculate the gradient multi-scale local phase quantization (GMLPQ) feature set of the face image described in ①. GMLPQ feature extraction p...
