centroid vector 解釋
質心向量, 分類向量
  • centroid : n. [物]矩心；質心，質量中心（＝centre of mass） 形心曲線；心跡線。
  • vector : n 1 【數學】向量，矢量，動徑。2 【航空】飛機航線；航向指示。3 【天文學】幅，矢徑。4 【生物學】帶...
  1. We presented a novel method of searching for similar fragments of 3d curves, with this method, a hash vector is associated with each fixed - length fragments of 3d sherd. each vector consists of low frequence component of fourier - like spectrum for the distance between profile curve and the centroid

    討論了基於hash矢量和fourier變換的輪廓曲線匹配方法，在匹配中不要求一段輪廓線與另外一段輪廓線完全匹配，而是把它們分成很多子段，再用這些子段來進行匹配。
  2. Draw the gait outline of people subtraction we received, and calculate the outline centroid. then we obtain n dots at the outline, calculating the normalized distances of the dots we obtained with the centroid, and the distances constitute the input vector

    將步態檢測得到的人的剪影提取輪廓，計算輪廓質心。取得輪廓上若干點，把提取的邊界點與質心點的歸一化距離作為輸入向量。
