[0039] A complex environment face detection method based on visual saliency, the implementation framework is as follows figure 1 shown. First, use the visual attention mechanism to obtain the face saliency map; then segment the saliency map to obtain the binary template; use the morphological operator to adjust the binary template to cover the entire face area; finally match the template with the original image to detect the face target area.
[0040] The specific implementation process of this complex environment face detection method based on visual saliency is as follows: figure 2 shown. The steps are described as follows:
[0041] S1. The input image is a 250×250 grayscale image I(x, y), and the saliency map of the target face area is extracted using the visual saliency map algorithm, which is denoted as S(x, y).
[0042] S2. Use the bicubic interpolation algorithm to adjust the size of the S(x,y) image to the original image size of 250×250, divide each pixel in S(x,y...
