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
給出了曲線參數速度的legendre多項式逼近,進一步給出了參數速度的插值區間端點的jacobi多項式逼近,由此導出了保持法矢平移方向的兩個等距代數有理逼近演算法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法實現了對掃描圖像中具有同一線型但不同線寬的線狀要素進行分類,在同一層上得到同一線寬的二值線狀要素圖;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法,用該演算法對實際的線狀要素進行細化,避免了端點、孤立點等信息的丟失,且由於是并行處理,有效地提高細化速度;對于細化后的骨架線,提出了基於freeman鏈碼的動態改變步長保持精度跟蹤矢量化方法。
