Embodiment Construction
[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] Such as figure 1 As shown, the high-dimensional local binary pattern face recognition algorithm of the embodiment of the present invention comprises the following steps:
[0048] S1. Obtain a face image, and preprocess it to obtain a grayscale image of the same size; the method of preprocessing to obtain a grayscale image is specifically:
[0049] Let the distribution of the local texture V of the face grayscale image be:
[0050] V=v(g c g 0 … g p-1 g)
[0051] Among them, g c Represents the central threshold of the window, g k where k=0,2...p-1, g k Represents the gray value of...
