  6. 3. by using the techniques of an explicit criterion to determine the number of real roots of a univariate polynomial in ( [ 13 ], [ 73 ] ) ; b - net form of bivariate splines function ; discriminant sequence of polynomial ( cf. [ 13 ], [ 73 ] ) and the number of sign changes in the sequence of coefficients of the highest degree terms of sturm sequence, this paper determines the number of real intersection points two piecewise algebraic curves whose common points are finite. a lower bound of the number of real intersection points is obtained in terms of method of rotation degree of vector field

    大連理工大學博士論義：分片代數價線i片代數簇的若十m穴3 ：利用楊路，張景中，侯曉榮在文獻v13 ， 73 ）中關於一元多項式實根的顯式判準，以及二元樣條函數的b網形式，多項式的判別序列和sturm序列的最高次數項系數序列的變號數，本文給出了兩個分片代數曲線的丈交點數（假設公共點是有限的）的計算公式。
  7. He analysed the results using a technique called discriminant function analysis

    博士用一種叫做判別函數分析的方法對結果進行研究。
  8. Firstly this paper introduced the principle of fisher linear discriminant function, and then present the subspace lda algorithm which project the data that is in high dimension space to eigenspace that is in low space and then maximize discriminant coefficient

    本文介紹了fisher線性判別準則原理和實現過程，然後引入subspacelda方法，用pca將高維圖像數據投影到低維的特徵臉空間，再用lda最大化判別系數。
  9. By comparing the image - preprocessing results of different processing algorithms, an optimized algorithm was decided to ensure satisfying correlation snr and preprocessing rate to be obtained. synthetic discriminant function ( sdf ) filters of the 3 - d targets were designed and the reference filter libs ( rfl ) were constructed to provide high correlation snr. real - time distortion - invariant optical correlation was realized by temporal - spatial multiplexing technique

    為了保證opr系統有高的相關信噪比（ snr ）及良好的實時性能，本文對不同圖像預處理演算法的處理性能及效果進行了比較分析，為opr系統選取恰當的圖像預處理演算法提供了依據；將時間多重化技術與空間多重化技術相結合，設計製作了三維目標的可實時刷新的sdf參考濾波器庫，為opr系統提供了高snr的相關輸出，從而實現了opr系統對目標的實時畸變不變光學相關；將人工神經網路（ ann技術）用於相關信號后處理，有效提高了opr系統的識別效率。
  10. So this paper based on fisher discriminant function estimating images similarity, and determine similarity queue of all images in database and query image

    因此本文依fisher判別函數來判定圖像相似度，決定數據庫中所有圖像與查詢圖像的相似隊列。
  11. It redefines the between - class scatter by adding a weight function according to the between - class distance. therefore, it can separate the classes as much as possible. at the same time, it projects the between - class scatter into the null space of the within - class scatter that contains the most discriminant information

    新方法重新定義了樣本類間離散度矩陣，在原始定義的基礎上增加一個由類間距離決定的可變權函數，使得在選擇投影方向時，能夠更好地分開各個類的樣本。
