摘要
不同时间段拍摄的自然山体图像存在不同的大气退化影响 .在这些图像的不同部分 ,大气退化影响的程度也不同 .这类图像的大气退化特征直接影响了图像的对比分析和理解 .文中探讨了自然山体图像由于大气原因而产生的退化现象 ,分析了图像的视觉特征 ,建立一个统一的基于输运理论的模型 .该模型可以在
There are different atmospheric degradation levels among different parts of a terrain photo. Also terrain photos taken at different moment show different atmospheric characters. Such kind of atmospheric degradation influence blocks the further image analysis and understanding. This paper explores the influence that atmospheric degradation exerts on the illumination and brings forward a transport theory based HSV model that expresses the change of value, saturation and hue .We adopt them to process the picture of nature terrain and the restoration result is satisfying.
