基于亮度特性的高空间分辨率遥感影像阴影处理研究
Processing Methods and Verification Examples of Shadows from High-resolution Satellite Images
摘要
Abstract
In the high-density urban environment, building shadows can block a lot of important information, resulting in inaccuracies or even errors in image interpretation. According to the geometric and spectral characteristics of the shadow image, this paper uses a brightness-based method, which chooses bimodal curve to select the appropriate brightness threshold to split the shadow and light areas. Then, it uses a linear mapping grayscale shadow compensation method to compensate the information of the shadow region. At last, the sample shadow data from the high spatial resolution remote sensing image are used to verify the effectiveness of the method. The results show that this method is effective.关键词
