Dynamic Time Warping (DTW) has been successfully used for crops mapping due to its capability to achieve good classification results when a reduced number of training samples and irregular satellite image time series is available. Despite its recognized advantages, DTW does not account for the duration and seasonality of crops and ...
WebMar 1, 2024 · TWDTW was used to classify the crop samples in TA1 and TA2. Dynamic Time Warping (DTW) is a nonlinear warping algorithm that compares the similarity between two temporal patterns and finds their optimal alignment (Sakoe and Chiba, 1978). It is a time-flexible method ideal to compare two temporal growth patterns of crops … WebJun 1, 2024 · In this study, the Time-Weighted Dynamic Time Warping method was applied to recognize patterns in Moderate Resolution Imaging Spectroradiometer …
