⚠️There's a newer version (1.0.0) of this package.Take me there.

dtwSat (version 0.1.0)

Time-Weighted Dynamic Time Warping for Remote Sensing Time Series Analysis

Description

Provides a Time-Weighted Dynamic Time Warping (TWDTW) algorithm to measure similarity between two temporal sequences. This adaptation of the classical Dynamic Time Warping (DTW) algorithm is flexible to compare events that have a strong time dependency, such as phenological stages of cropland systems and tropical forests. This package provides methods for visualization of minimum cost paths, time series alignment, and time intervals classification.
