Dynamic Time Warping Algorithm with Adaptive Weighting of Extreme Points [PDF]

open access: yesJisuanji gongcheng, 2023
To solve the problem of large computation and high time complexity of the Dynamic Time Warping(DTW) algorithm, a novel DTW algorithm with adaptive weighting of extreme points, called EWDTW, is proposed.The fluctuation of local extreme points reflects the

Seeded Classification of Satellite Image Time Series with Lower-Bounded Dynamic Time Warping

open access: yesRemote Sensing, 2022
Satellite Image Time Series (SITS) record the continuous temporal behavior of land cover types and thus provide a new perspective for finer-grained land cover classification compared with the usual spectral and spatial information contained in a static ...

Improved LDTW Algorithm Based on the Alternating Matrix and the Evolutionary Chain Tree

open access: yesSensors, 2022
Dynamic time warping under limited warping path length (LDTW) is a state-of-the-art time series similarity evaluation method. However, it suffers from high space-time complexity, which makes some large-scale series evaluations impossible.

Similarity Measure Based on Incremental Warping Window for Time Series Data Mining

open access: yesIEEE Access, 2019
A similarity measure is one of the most important tasks in the fields of time series data mining. Its quality often affects the efficiency and effectiveness of the related algorithms that need to measure the similarity between two time series in advance.

Efficient alignment-based average delay time estimation in fluctuating delayed propagation

open access: yesArray, 2022
We propose an alignment-based average delay time estimation algorithm between two time series in the propagation of time-varying delay. Though the number of the minimum cost alignments may be exponential in the length of the time series, the proposed ...

Simultaneous Localization and Recognition of Dynamic Hand Gestures [PDF]

open access: yes, 2004
A framework for the simultaneous localization and recognition of dynamic hand gestures is proposed. At the core of this framework is a dynamic space-time warping (DSTW) algorithm, that aligns a pair of query and model gestures in both space and time. For
