VEGETATION植被指数数据预处理方法

Data Pre-processing Method Using VEGETATION Plant Indicator

VEGETATION数据的植被指数,受云雾影响,含有大量的噪声信号,使用之前必须进行去噪声处理。结合实例数据介绍了半中值滤波法、半均值滤波法、等间隔极大值法用于植被指数的去噪声处理,效果良好;该处理方法同样适用于NOAA和MODIS等数据的植被指数预处理。

Due to the impact from cloud and mist,the plant indicator on VEGETATION data contains substantial noise signal.So,the Processing to remove the noise must be carried out before using it.Combined with the actual examples,the semi-intermediate value wave filtering method,semi-average value wave filtering method,and equal space MVC have been introduced,and have good results when being used in noise removal processing of plant indicator.Similarly,this processing method can be applied in plant indicator pre-processing for NOAA,MODIS data,etc.
