缺少水陆标识数据情况下MODIS图像云检测的实现

Cloud Detection of MODIS Image without Land/Sea Mask

云检测中必须进行像元的水陆判识,云的存在给水陆判识带来了困难。因此,云检测中总是利用水陆标识数据辅助云检测。本文讨论了缺少水陆标识数据的云检测方法,并证明了该方法可行、实用。

Before the cloud detection every pixel must be marked as water or land, So the land/sea mask data are every important in the cloud detection. This article describes a method which realizes cloud detection without the land/sea mask data and proves that it is practicable.
