dynamic time warping

动态时间规整：动态时间规整（DTW）是一种用于衡量两个时间序列相似性的算法，这两个序列可能在速度上有所不同。例如，使用DTW可以检测出行相似性，即使一个人走得比另一个人快，或者在观察过程中有加速和减速。DTW已应用于视频、音频和图形数据的时间序列，事实上，任何可以转化为一维序列的数据都可以用DTW进行分析。一个著名的应用是自动语音识别，用于应对不同的说话速度。其他应用包括说话人识别和在线签名识别。它还可以用于部分形状匹配应用。

abstract: in time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences which may vary in time or speed. For instance, similarities in walking patterns 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 observation.
