| 摘 要： | 在恶劣天气条件下获得的户外场景图像往往存在较差的对比度和颜色,严重影响了对图像的分析和理解。文中简要分析了此类图像退化的原因,并引入了大气辐射传输方程来研究散射现象。利用Narasimhan和Nayar提出的数值解来进行图像复原的实现,并基于此数值解,提出了针对恶劣天气的改进计算。实验表明,改进后的数值解对退化图像能得到很好的恢复效果,减少了计算量。

| Abstract: | Images of outdoor scene, which acquired in bad weather, degraded with poor contrast and color. It influence image analysis and understanding seriously. This paper analyze the reason of degradation, and using RTE to reseach on scattering phenomenon. Realize the numerical value solution, which presented by Narasimhan and Nayar, in image restoration. Present a improved calculate method. The result of improved solution is satisfy, especially decrease the calculation. |
