[0032] See Figure 1 for the implementation flow diagram of the adaptive image enhancement method. The image enhancement method is implemented based on the correlation coefficient algorithm and the optimal visual performance theory, including the following steps: firstly, the image is processed by low-pass filtering, and then the high-pass filter is obtained. frequency images. The high-frequency image is sequentially adaptively sharpened and the contrast adjusted to obtain an enhanced image. Wherein, referring to the detailed diagram of the implementation process of the method shown in Figure 2, when the original image is subjected to low-pass filtering processing, the first layer of low-frequency image A is obtained 1 , with the original image and A 1 Perform vector subtraction to obtain the first layer high-frequency image E 1 , similar to this, to get the second layer low-frequency, high-frequency image A 2 ,E 2 And layer 3 low frequency, high frequency image A 3 ,E 3 ...
