Off-line signature verification using DTW

Pattern Recognition Letters, 2007
In this paper, we propose a signature verification system based on Dynamic Time Warping (DTW). The method works by extracting the vertical projection feature from signature images and by comparing reference and probe feature templates using elastic matching.

Quantized Dynamic Time Warping (DTW) algorithm

2010 8th International Conference on Communications, 2010
DTW algorithm compares the parameters of an unknown spoken word with the parameters of one or more reference templates. The more reference templates are used for the same word, the higher is the recognition rate. But increasing the number of reference templates for the same word to recognize, leads to an increase in memory resources and computing time.

A combined filtering search for DTW

2017 2nd International Conference on Image, Vision and Computing (ICIVC), 2017
Due to its high matching precision, DTW is an important similarity measure for time series. However, the high computational complexity restricts its application on mass data sets. To solve the problem, a combined filtering search is proposed, which combines lower-bounding technique and early-abandon strategy, to reduce the redundant computation.

New parallel implementations for DTW algorithms

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1990
The parallel realization of a popular dynamic time warping (DTW) algorithm is discussed. Two alternative techniques are proposed, one based on a circular array and the other using a linear array of processing elements (PEs). The architecture of each PE is defined in both cases and computational phases are outlined.

A Robust Fault Isolation Method Based on DTW

IFAC Proceedings Volumes, 2006
Abstract The precise mathematical model of industrial process is difficult to be obtained, so a fault isolation method independent of process mathematical model is proposed. This method is based on dynamic time warping (DTW) technology and isolates process fault by process data analysis .

DTW - Mastbullenhaltung – Alternativen in der Spaltenbodenhaltung

Dtsch.tierärztl.Wschr., 2008
Gummimodifizierte Spaltenboden bieten auch fur intensiv gehaltene Mastrinder einen groseren Liegekomfort, ein geringes Risiko fur Gelenk- und Schwanzverletzungen als auch eine bessere Trittsicherheit bei Bewegung. Jedoch treten aufgrund fehlenden Hornabriebs mehr Zerkluftungen an Sohlen- und Ballenhorn auf, die "wilde" Uberwachsungen des Tragrandes ...

Learning DTW-Shapelets for Time-Series Classification

Proceedings of the 3rd IKDD Conference on Data Science, 2016, 2016
Shapelets are discriminative patterns in time series, that best predict the target variable when their distances to the respective time series are used as features for a classifier. Since the shapelet is simply any time series of some length less than or equal to the length of the shortest time series in our data set, there is an enormous amount of ...
