Automatic Smoothing of Remote Sensing Data
We present a fast smoother and interpolator for time series. It is based on Whittaker smoother. The amount of smoothing is optimized with the so-called V-curve, a variation on the L-curve. The algorithm is very fast, thanks to the use of sparse matrices. It handles (even many) missing data points with ease. Envelopes can be estimated by expectile smoothing.
