This paper presents a phenology-preserving filtering method as a significant improvement to the standard changing-weight filter method to reduce noise in NDVI time series. Specifically it introduces two new features: (1) replacing the changing-weight filter with a 3-point Gaussian filter to improve the computing efficiency; and (2) introducing a multi-year average NDVI time series to remove the false local minima points. This phenology-preserving filtering method was tested at 178 test points… CONTINUE READING
