Embodiment 1
[0082] This embodiment provides an image restoration method based on visual selection fusion, such as figure 1 As shown, the method includes:
[0083] The threshold characteristic information of the sky region segmentation of the foggy image is obtained through the statistical model, and the effective range of the global atmospheric background light value is obtained by segmenting the sky region of the foggy image according to the threshold characteristic information;
[0084] Obtain the initial transmittance image of the foggy image, and use the adaptive boundary limit L0 gradient minimization filter method to optimize the transmittance image;
[0085]Within the effective range of the global atmospheric background light value, input the optimized transmittance image into the dark channel theoretical model, and use the dark channel theoretical model to obtain multiple restored initial defogged images; construct a method based on visual selection to select from each Select the...
