Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0027] Such as figure 1 As shown, the present invention provides a kind of facial feature recognition method of frequency domain division, comprising:
[0028] S101. Perform FFT transformation on the training image X to obtain the frequency distribution F=FFT(X). Specifically, the storage of the image X in the computer is a three-dimensional array, which is respectively channel (channel), height (height), width (width) ); wherein the image in the RGB format has 3 channels, respectively corresponding to Red, Green, and Blue, and fast Fourier transform is carried out for each channel, i.e. FFT transform, because the FFT change is a technology known in the art, here will not repeat;
[0029] S102. Divide the frequency dist...
