结合边界约束和引导滤波的航空图像去雾算法
Aerial image haze removal algorithm based on boundary constraint and guided filter
摘要
Abstract
In fog weather conditions,contrast and color fidelity of aerial image are poor due to the scattering of the atmosphere particles.A fast defogging method combined with boundary constraint and guided filter in the aerial image is proposed.The method based on the principle of dark channel is used to estimate the atmospheric light intensity.By adding the boundary constraint condition and solving the objective function to calculate the transmission,and then refining the transmission by the guided filter to get the purpose of defogging,the results show that compared with the methods of Fattal,Tarel,He and Meng algorithm,the speed of the proposed method is fast.It can improve the detail clarity and increase the depth of defogging.What is more,it can overcome the color saturation phenomenon effectively and the defogging images are natural and realistic.关键词
