Embodiment Construction
[0043] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0044] Such as figure 1As shown, the invention provides a kind of identity recognition method based on the fusion of multimodal biometric characteristics of evolutionary strategy, which method comprises the following steps:
[0045] (1) Collect the image data of three biometric features of face, static hand shape and palm print, and perform feature recognition and authentication on the image data of each biometric feature collected; the specific steps are as follows:
[0046] (1.1) Biometric feature extraction: using principal component analysis (PCA) method, for a pixel M*N biometric image data, the M*N pixel matrix is arranged in columns, and then transposed , forming an image vector with a size of D=M*N dimensions, collecting n pieces of biometric image data as training samples to form a training image library, x i The image...
