Embodiment Construction
[0102] In order to better understand the technical solution of the present invention, the following further describes the embodiments of the present invention:
[0103] The present invention is implemented under the Microsoft Visual Studio 2008 language environment. The computer reads the original foggy image, first calculates the dark channel image of the input image and estimates the global atmospheric light value through the dark channel image, then roughly estimates the atmospheric dissipation function, and then uses Gaussian filtering to perform a rough estimation of the atmospheric dissipation function refinement, and finally calculate the scene irradiance with an improved algorithm.
[0104] The present invention is a single image defogging method based on Gaussian filtering, the flow of the method is shown in figure 1 shown. The method includes the following steps:
[0105] Step 1: Read the original foggy image I(x), "calculate the dark channel image and estimate th...
