  1. After giving the legendre polynomials approximation to parametric speed of the curve, the author gives the jacobi polynomials approximation to parametric speed with endpoints interpolation. from this, two algebraic offset approximation algorithms, which preserve the direction of normal, are derived

    給出了曲參數度的legendre多項式逼近,進一步給出了參數度的插值區間點的jacobi多項式逼近,由此導出了保持平移方向的兩個等距代數有理逼近演算
  2. The paper, in the way of math morphology, manages to classify the linear elements, the same type but different width in the scanning, and result in the two - valued linear image in the same level. in the fine division of the target image, a way of math morphology based on the double structure of cell stencil is put forward, which prevents the terminals and the acnodes from losing and also reduces effectively time in doing so. as the result of the framework of the fine division, vector method is formed in which its track is monitored by using dynamic change of pace about freeman ' s chain code

    本文用數學形態學相關理論方實現了對掃描圖像中具有同一型但不同寬的狀要素進行分類,在同一層上得到同一寬的二值狀要素圖;在對此目標圖像進行細化時,提出了基於雙結構單元模板的數學形態學細化演算,用該演算對實際的狀要素進行細化,避免了點、孤立點等信息的丟失,且由於是并行處理,有效地提高細化度;對于細化后的骨架,提出了基於freeman鏈碼的動態改變步長保持精度跟蹤量化方
