Fractal Signature Feature Analysis of MODIS NDVI Time Series Data

Fractal signature feature of MODIS Normalized Difference Vegetation Index (NDVI) time series data is proposed in this study in order to further mine its inherent information. Savitzky-Golay filter is adopted to reconstruct MODIS NDVI time series curves of Beijing in China. The blanket method used fo...
