Web动态时间扭曲（DTW）是一种计算两信号间路径的方法，它能最小化两信号之间的距离。 这种方法最大的优势就是他能处理不同长度的信号。 最初它是为了进行语言分析而被发明出来（在 这段视频 中你可以了解更多），DTW 通过计算每一帧对于其他所有帧的欧几里得距离，计算出能匹配两个信号的最小距离。 一个缺点就是它无法处理缺失值，所以如果你的 … Webefforts would like to use DTW, but find it very time-consuming [5,14,15,16]. Therefore, DTW is the right measure to accelerate. 2.3 Related Work . Accelerating DTW attracts thousands of research work in these decades, and almost all of them are software-based techniques. Y. Sakurai et al. propose a computation-reuse algorithm called SPRING [11].
