Abstract：The detection of cloud pixels is the essential for monitoring resources and environment of the earth using NOAA-AVHRRimage. The paper analyses the feature of the clouds on NOAA-AVHRRdata by instances, draws 3D-statistic graph according to the feature indexes, and decides the thresholds of cloud pixels directly from the graph. The thresholds are regarded as the setting condition for detecting the cloud pixels automatically. The advantages of above method are higher sensitivity and better stability and that the viewing for the distribution of cloud pixels is more directly.
