Description

The MATLAB script Weiner-filter-Main.m loads data of normalized movement statistics and normalized NDVI. It subsections data into continuous time sections of no more thatn the chosen segment length (e.g., 1000 hours). The first half of the data is used for choosing the filter coefficents and the second half is used for evaluating performance.

The MATLAB script Weiner-filter-Compare.m uses filters created for one data set to predict a different data set. The script loads data and analyzes filter performance based on temporal, seasonal, or spatial restrictions, or a combination thereof. Results are output as box plots.
