摘要

A cloud detection method based on Landsat 8 snow-containing image, including the following steps: Step 1, selecting any Landsat 8 image as a current image; Step 2, obtaining a cloud threshold for delineating a cloud range from the current image; and Step 3, removing false anomalies in the cloud range delineated by the cloud threshold from the current image so as to obtain a cloud image from which the false anomalies have been removed. The present disclosure can effectively solve the problem of confusion of cloud and snow present in conventional cloud detection methods, and is applicable to regions of different latitudes, without limitations by the amount of cloud.
