【摘要】 在二色大气散射模型的基础上,根据雾对景物退化与景物深度的指数关系,采用交互方式,通过附加一些主观判断作为先验信息,从单幅图像中估计出景物深度,进行对比度增强,有效实现了彩色图像去雾。同时针对浓雾退化图像处理结果较暗的情况,进行了正态截取拉伸,提高了图像亮度,获得了较好的视觉效果。更多还原

【Abstract】 According to the exponential relationship between the degradation of the image and the depths of the scene points, a method was proposed to estimate the scene depths from a single image using simple additional prior information provided interactively by the user with his subjective discretion. So based on the dichromatic atmospheric scattering model, chromatic image defogging was implemented effectively through contrast enhancement. As the intensity of the processing output of the image degraded by dense fog was weak, the normal clipped stretching method was deployed to enhance the image brightness, and satisfying results were got.更多还原
