Fastdtw - Dynamic Time Warping (DTW) with a linear time and memory complexity

FastDTW is an approximate Dynamic Time Warping (DTW) algorithm that provides optimal or near-optimal alignments with only O(N) time and memory requirement, in contrast to the O(N^2) requirement for the standard DTW algorithm. FastDTW uses a multilevel approach that recursively projects a solution from a coarser resolution and refines the projected solution. Implementation: FastDTW is implemented in Java. If the JVM heap size is not large enough for the cost matrix to fit into memory, the impleme

Dynamic Time Warp for Time Series Analysis

This is a conversion to C# of Stan Salvador, Philip Chan Fast DTW algorithm originally implemented in Java.

Lbimproved - Fast Nearest-Neighbor Retrieval under the Dynamic Time Warping

This C++ library implements fast nearest-neighbor retrieval under the dynamic time warping (DTW). This library includes the dynamic programming solution, a fast implementation of the LB_Keogh lower bound, as well as a improved lower bound called LB_Improved. This library was used to show that LB_Improved can be used to retrieve nearest neighbors three times on several data sets including random walks time series or shape time series. Code sample: #include "dtw.h" (...) // compute the DTW between

Aquila - C++ DSP library

Aquila is a digital signal processing library written in C++. Features: reading input files in WAVE format, 8 or 16-bit per sample, mono or stereo, with almost any sample frequency dividing input signals into short frames and applying mathematical transformations to each frame calculating energy, power, FFT and DCT of a signal feature extraction, including MFCC and HFCC features, widely used in speech recognition a simple DTW (dynamic time warping) pattern matching algorithm which also can be us
