HybridFTW: Hybrid Computation of Dynamic Time Warping Distances
IEEE Access, 2018 In this paper, we propose an efficient approach that computes the dynamic time warping (DTW) distance in time-series similarity search. The DTW distance is known to offer the high accuracy in similarity search, but it has difficulty in supporting the ...

Hybrid Method for Digits Recognition using Fixed-Frame Scores and Derived Pitch [PDF]
, 2006 This paper presents a procedure of frame normalization based on the traditional dynamic time warping (DTW) using the LPC coefficients. The redefined method is called as the DTW frame-fixing method (DTW-FF), it works by normalizing the word frames of the ...
