Warp, v. i. [OE. warpen; fr. Icel. varpa to throw, cast, varp a casting, fr. verpa to throw; akin to
. Dan. varpe to warp a ship, Sw. varpa, AS. weorpan to cast; cf. Skr. vrj to twist. Cf. Wrap.]
1. To turn, twist, or be twisted out of shape; esp., to be twisted or bent out of a flat plane.
2. to turn or incline from a straight, true, or proper course; to deviate; to swerve.
3. To fly with a bending or waving motion; to turn and wave, like a flock of birds or insects.
-----------------------------------------------
Warp, n. [AS. wearp; akin to Icel. varp a casting, throwing,
. Sw. varp the draught of a net, Dan. varp a towline, OHG. warf warp, G. werft.]
1. (Weaving) The threads which are extended lengthwise in the loom, and crossed by the woof.
3. (Agric.) A slimy substance deposited on land by tides,
6. [From Warp, v.] The state of being warped or twisted; as, the warp of a board.
. Warp beam, the roller on which the warp is wound in a loom.

<<The terms time warp, space warp and time-space warp are commonly used in science non-fiction. They sometimes refer to Einstein's theory that time and space form a continuum which bends, folds or warps from the observer's point of view, relative to such factors as movement or gravitation, but are also used in reference to more fantastic notions of discontinuities or other irregularities in spacetime not based on real-world science. In science fiction, "warp drive" is often a name given to travel faster than the speed of light. Notably in the Star Trek television series Warp Factor is a name given to the number of times faster than light the fictional spacecraft has effectively moved.>>

<<Dynamic time warping is an algorithm for measuring similarity between two sequences which may vary in time or speed. For instance, similarities in walking patterns would be detected, even if in one video the person was walking slowly and if in another he or she were walking more quickly, or even if there were accelerations and decelerations during the course of one observation. A well known application has been automatic speech recognition, to cope with different speaking speeds.
In general, DTW is a method that allows a computer to find an optimal match between two given sequences (e.g. time series) with certain restrictions. The sequences are "warped" non-linearly in the time dimension to determine a measure of their similarity independent of certain non-linear variations in the time dimension. This sequence alignment method is often used in the context of hidden Markov models. DTW is an algorithm particularly suited to matching sequences with missing information, provided there are long enough segments for matching to occur.
The extension of the problem for
two-dimensional "series" like images (planar warping) is NP-complete,
while the problem for one-dimensional signals like time series can be solved in polynomial time.>>
