The DTW lower bound and its discrete wavelet transform of query sequence were computed to form a query super-rectangle, thus the similar matching in original space based on DTW was converted to that in wavelet transform space based on Euclidian distance.

 
  • 給出了查詢(xún)序列的DTW距離邊界和其在小波空間的查詢(xún)超矩形的計算方法;從而將原始空間的基于DTW距離的相似匹配轉換為小波空間基于歐氏距離的相似匹配.
