Embodiment Construction
[0058] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0059] figure 1 Shows the implementation flow chart of the image defogging method including a large sky area provided by the present invention, which specifically includes the following steps:
[0060] In step S101, quadtree segmentation is performed on the photographed foggy image I(x), the foggy image is divided into a plurality of image regions, and seed points are obtained in the plurality of image regions.
[0061] In this step, in order to find the sky area in the foggy image, the quadtree segmentation algorithm is used to process the foggy image, namely:
[0062] First, the foggy image is ...
