Embodiment 1
[0120] The classification model is a segmentation hyperplane.
[0121] In this example, given a set of point sets (features) in a separable space, there must exist a hyperplane π: ω·x+b=0 that can transform these features x i , i=1,...,n are divided into two different categories.
Embodiment 2
[0123] The classification model is a kernel function.
[0124] In this embodiment, for nonlinear classification problems, the processing method of SVM is to select a kernel function, and solve the problem of linear inseparability in the original space by mapping the data to a high-dimensional space.
[0125] In any of the above embodiments, preferably, the formulas of the first dark channel image and the second dark channel image are:
[0126]
[0127] Among them, J c Represents the R, G, B color channels of the image, Ω(x, y) represents the image block centered on the pixel (x, y), and (x, y) represents the coordinate value of the image pixel.
[0128] Such as Figure 11 As shown, the left column is the original image, and the middle column is the dark channel image corresponding to the original image. It can be seen from the figure that the gray value of the dark channel image of the polluted image is higher than that of the uncontaminated image. To describe the charac...
