Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] like figure 1 As shown, a schematic diagram of an identification sample library model, the entire sample library is divided into M layers from bottom to top, each layer can establish multiple sub-sample library nodes, and the order of magnitude of the sample library contained in each sub-sample library node is less than or equal to N, where, N is the order of magnitude of the effective sample library supported by the face recognition algorithm, and the sub-sample library nodes established in each layer from the bottom up are the abstract induction of the sub-sample library nodes in the lower layer, that is, the sub-sample library nodes in each layer The library nodes are respectively connected to the sub-sample library nodes in the bottom layer. In addition, the number of sub-sample library nodes contained in each layer is smaller than...
