savitzky-golay to daily MODIS time-series (google.com)
先附上OEEL上的Sg滤波模块,文末有我的sg滤波实现代码:
链接:Documentation Open Earth Engine Library (open-geocomputing.org)
oeel.ImageCollection.SavatskyGolayFilter(...)
oeel.ImageCollection.SavatskyGolayFilter(collection, filter, distanceFunction, degree, bandOfInterest, EstimationCollection, Return)SavatskyGolayTimeFilter. Pass a Savatsky-Golay filter along the image collection
Arguments:

博客介绍了如何使用Savitzky-Golay滤波器对OpenEarthEngine库中的 SentinelNDVI 数据进行平滑处理。通过oeel.ImageCollection.SavatskyGolayFilter()函数,可以应用滤波器来减少噪声并提取时间序列数据的趋势。示例代码展示了具体实现步骤,并提供了实际应用MODIS数据的示例。
