In time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences, which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and decelerations during the course of an ...
In comparison to other distance measures, (e.g. DTW (dynamic time warping) or LCS (longest common subsequence problem)), TWED is a metric. Its computational time complexity is O ( n 2 ) {\displaystyle O(n^{2})} , but can be drastically reduced in some specific situations by using a corridor to reduce the search space.
A timewarp is a tool for manipulating the temporal dimension in a hierarchically described 3D computer animation system. The term was coined by Jeff Smith and Karen Drewery in 1991. [1]
GTW considers both the alignment accuracy of each sequence pair and the similarity among pairs. On contrary, alignment with dynamic time warping (DTW) considers the pairs independently and minimizes only the distance between the two sequences in a given pair. Therefore, GTW generalizes DTW and could achieve a better alignment performance when ...

The time warping functions are assumed to be invertible and to satisfy (()) =. The simplest case of a family of warping functions to specify phase variation is linear transformation, that is h ( t ) = δ + γ t {\displaystyle h(t)=\delta +\gamma t} , which warps the time of an underlying template function by subjected-specific shift and scale.
