在本文中,我们提出了一个水平集方法来识别城市地区使用的夜间光数据的Suomi国家极轨合作伙伴(NPP)可见光红外成像辐射计套件(VIIRS)。我们的方法相比,两个标准的方法,称为大津的阈值为基础的方法和k-均值聚类方法。实验结果表明,显着改善的Kappa系数。
In this paper, we propose a level-set method to identify urban areas using a nighttime light data of Suomi National Polar-orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS). Our method is compared to two standard methods, called the Otsu's threshold-based method and the k-mean clustering method. The experimental results indicates significant improvement in terms of the Kappa coefficients.
