  1. American journal of botany, 2003, 90 : 333 - 338. 19 fougerolle y d, gribok a, foufou s, truchetet f, abidi m a. boolean operations with implicit and parametric representation of primitives using r - functions

    在此,超形的表面以所允許的精度進行采樣生成,而它們的頂點和面片將根據隱函數的刻畫來決定它們是否用於最終實體表面的生成。
  2. Hust - caid ( computer aided industry design system developed by harbin university of science and technology ) is a parametric modeling design system based on feature. this system describes entities based on mixed model of boundary representation 、 csg tree and feature description tree ( fdt ), in which the design of solid model and feature - editing can be completed with rebuilding csg tree and feature description tree. but, in the feature modeling, with the number of features increasing, the design model becomes more and more complex. the efficiency of designing is decreased

    Hust - caid (哈爾濱理工大學計算機輔助工業造型設計系統)是一種基於特徵的參數化造型設計系統。該系統在基於b - rep 、 csg樹和特徵描述樹( fdt )的混合模型基礎之上,利用重用csg樹與特徵描述樹的技術,來完成實體模型的設計與編輯工作。但在特徵造型過程中,隨著造型體數目的增加,設計模型將變得越來越復雜,由此導致了系統設計效率的降低。
  3. In section 4. 2 we analyze its main idea and algorithm in detail, two relevant theorems included ; section 4. 3 provides plenty instances so to explain its nonlinear dimension reduction ability, section 4. 4 propose a combined method that integrates the advantage of various methods. in section 4. 5 we analyze some significant problems in lle, including the locality of manifold representation, the choice of the neighborhood, the intrinsic dimension estimation and the parametric representation of mapping. in section 4. 6 we design an algorithm for estimating the intrinsic dimension in the base of locally linear approximation and discuss the choice of its parameters

    第四章是本文的重點內容,研究一種全新的非線性降維方法? ?局部線性嵌入方法,對它的思想和演算法進行了詳細的分析,給出演算法兩個相關定理的證明;第三節對比主成分分析,通過實例說明局部線性嵌入方法的非線性降維特徵;第四節在此基礎上提出了旨在結合兩者優勢的組合降維方法;第五節提出了局部線性嵌入方法中存在的若干關鍵性問題,包括流形的局部性、鄰點的選擇、本徵維數的估計和降維映射的表示,第六節基於局部線性近似的思想提出了一種本徵維數的估計方法,設計了實用演算法,結合實例對演算法中參數的選取進行了討論;最後一節提出了一種基於局部線性重構的圖形分類和識別方法,將其應用於手寫體數字的圖像分類識別實驗,實驗得到的分類準確率達96 . 67 。
