Human Electrocardiogram for Biometrics Using DTW and FLDA

2010 20th International Conference on Pattern Recognition, 2010
This paper proposes a new approach for person identification and novel person authentication using single lead human Electrocardiogram. Nine Feature parameters were extracted from ECG in spatial domain for classification. For person identification, Dynamic Time Warping (DTW) and Fisher’s Linear Discriminant Analysis (FLDA) with K-Nearest Neighbor ...

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.

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 ...

Lip print recognition based on DTW algorithm

2011 Third World Congress on Nature and Biologically Inspired Computing, 2011
This paper presents a method of lip print recognition using the Dynamic Time Warping algorithm (DTW). The presented method consists of two stages. In the first stage lip print image is subjected to pre-processing which aims to distinct the lip pattern.

Enhanced DTW based on-line signature verification

2009 16th IEEE International Conference on Image Processing (ICIP), 2009
This work describes an enhanced technique for on-line signature verification. The distance between two signatures is computed by dynamic time warping (DTW) method. The reference signatures are used to assign special parameters for each signer, which makes the system cover the intra signer variation. Several features are extracted.

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 .

Speech recognition using MFCC and DTW

2014 International Conference on Advances in Electrical Engineering (ICAEE), 2014
Speech recognition has wide range of applications in security systems, healthcare, telephony military, and equipment designed for handicapped. Speech is continuous varying signal. So, proper digital processing algorithm has to be selected for automatic speech recognition system. To obtain required information from the speech sample, features have to be

Systolic multiple-valued DTW processor

1991 International Conference on Circuits and Systems, 2002
A new concept called 'recursive systolic flow' is proposed in this paper. It is adaptable to the formal algebraic design for complex systolic algorithm. A new systolic multiple-valued DTW (MV-DTW) processor is also presented which can achieve real-time isolated word recognition for large dictionaries.

Improving DTW for Online Handwritten Signature Verification

2004
Authentication by handwritten on-line signature is one of the most accepted authentication system. In a way, it is based on biometrics. It is embedded in our cultural habits and easy to use. The aim of this paper is to study two possible improvements in Dynamic Time Warping: matching process and distance computation.
