[0060] The present invention will be described in detail below in conjunction with specific embodiments.
[0061] 1.1 Algorithm flow design
[0062] If the semi-reverse defogging detection algorithm of Codruta O et al. [11] is used to obtain the overall atmospheric light value, the estimated overall atmospheric light is more robust than simply using the brightest point of the image, but its subsequent layer-based The effect of defogging algorithm is not ideal. Because the algorithm is in the process of weighting and summing different layers, the layer weight ratio is inconvenient to set, and the contrast of the fog-free area has not been improved well. Therefore, in order to overcome the deficiencies of the fusion algorithm method based on different illumination layers, the present invention uses an improved semi-inverse algorithm to obtain the overall atmospheric illumination value, and then uses the method of image edge information and smooth area fusion to estimate the atmosphe...
