currency matching 中文意思是什麼
-
Gained same data with literature. paper based cascade scatter matrix field matching equation. program currency frame grating programme. obtain several design project of high power and high efficiency grating - circular polarization
分析了薄片型光柵圓極化器的傳輸特性和極化特性，數值計算的結果與文獻給出的實驗測得結果具有較好的一致。 -
In the case of an organized exchange like the chicago mercantile exchange in the us, standardized currency contract sizes that represent a certain monetary value are traded in the international money market. a central clearing house organizes matching of transactions between counter - parties
在一般有組織的交易的情況下，如美國芝加哥商品交易市場，標準的外匯合同規范了一定數量的貨幣在國際貨幣市場的交易，交易市場提供一個清算的空間以便完成櫃臺交易者之間的各項交易。 -
The target is that it begins with the information of the graph ( based on pdm ) used to directly depict parts, being supported by the currency cad / cam system, receiving the producing information by interact with manual, matching the cutter with expert system, building the data of the cutter location ( cl ) by account, finishing the optimising arrangement, creating the nc program for the numerical control system of the fms - ii of sheet metal by the post system, automatically processing the produce by the nc machine tool according to the cl, and then realizing the opening integration of the system of cad / cam system of the fms - ii for sheet metal, basing on pdm
為了解決這些問題，需要重新開發fms -的cad cam系統，目標就是從基於pdm下的通用cad系統提供的圖形信息直接描述零件開始，人工交互方式輸入加工信息，由專家系統的推理機實現自動配模，經計算產生刀位文件，優化排料后，再針對鈑金fms -的數控系統，後置處理生成相應的數控加工程序，數控機床根據加工程序代碼自動完成加工，從而實現鈑金fms -的cad cam系統基於pdm下的開放集成。 -
First classifier chooses two classes whose matching distance between it and paper currency is bigger than others from all class. then in the second stage, we extract some new feature and improve the classifier to generate the last result. in the stage of defect detection for paper currency, we advances a homogeneity based algorithm for the detection of scratch and cracks appearing on paper currency, in which the homogeneity feature of the sensed paper currency image is first constructed to locate the pixels that probably been polluted, the image registration algorithm is subsequently used to overlay the sensed and reference paper currency image
在特徵提取中，我們對基於方向塊的特徵提取方法進行了分析，在此基礎上針對美元特點，對圖像方向塊的劃分方式做了研究，並提出了基於幾何距離的特徵提取方法;在分類器設計中，我們採用了lvq網路對紙幣進行學習與分類，並提出了一種具有兩層結構的分類演算法，第一層首先對輸入的特徵向量進行粗分類，選定與特徵向量匹配距離最大的兩類幣種，進入第二層分類器;在第二層分類器中，我們通過研究進入該模塊兩類幣種特徵塊的相關性，重新設計了特徵向量，同時對分類器進行改進，最終實現對紙幣的分類。
