Embodiment Construction
[0024] Embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0025] figure 1 A general flow chart of the face detection method according to the embodiment of the present invention is shown. Such as figure 1 As shown, the face detection method S10 of the embodiment of the present invention includes: an importing step S100, which can import an image to be processed; a sub-image extraction step S200, which can use windows of different scales to respectively traverse the image to be processed, and extract the image to be processed in the window part, as a sub-image; preprocessing step S300, can use the horizontal Sobel template to calculate the Sobel image of the sub-image for the sub-image, if the sum of the Sobel response values of the predetermined area in the Sobel image is relative to the sub-image The ratio of the total Sobel response value of the total Sobel response value is less than predetermined ratio threshold val...
