“…Dynamic Time Warping (DTW) was initially introduced to recognize spoken words [7]. Since then it has been used and proved useful in different applications such as: handwriting recognition [6,8], signature verification [9][10][11][12], fingers print verification [13], face recognition [14,15], speech and gesture recognition [16], protein structure [17], gene expression [18,19], chromosome classification [20], object detection and classification [21,22], curve matching [23,24] control system [25], image and shape matching [24,26] database and data mining [27-29, 31, 32, 34-37), brain activity classification [38], voice control [39] and so on. The DTW algorithm uses a dynamic programming technique to align time series with a given template so that a total distance measure is minimized [25].…”
