  1. The traffic zone split is studied deeply. the research regards the critical distance of medium - long distance trip as the centroid distance between the two adjoining traffic zones, and uses this critical distance as the equivalent diameter to estimate the area of the traffic zone

    對快速路系統規劃的交通小區劃分進行了深入研究，提出將大城市中長距離出行的這一界定值作為相鄰兩交通小區形心之間的距離，用這一臨界距離值作為交通小區的等價直徑值來估算小區規模。
  2. Centroid of area

    面的形心
  3. For every point on contour curves, the support area and support radius were first calculated based on actual distance of adjacent pixels, end points were obtained with linear interpolation technique ; next, the distance between point and its centroid of support area was used as feature strength to determine feature points candidate ; finally, those points with local maximum feature strength were selected as vertices of polygonal

    摘要首先基於相鄰像素間的歐氏距離計算出輪廓曲線上每一點的支持區域及支持半徑，用線性插值得到支持區域的端點；然後求得支持區域的質心，以曲線上的點和其相應的支持區域質心之間的距離作為特徵響應篩選出候選特徵點；最後將具有局部極大特徵強度的點作為多邊形的頂點。
