So we can utilize the special sensor data to create the currency feature collection via analyzing currency samples in statistics. the fake currency can be identified rapidly and exactly by this method
利用特殊的傳感器數據，通過對貨幣樣本的統計分析建立貨幣的特徵模式集，實現對真偽的快速、準確識別。 -
It is known that if there is defection on the glass - shell, it must be identified exactly. in order to extract the defect, some image segmentation methods are studied, such as differential histogram method, otsu method, and histogram method
為了將氣泡及劃痕等缺陷從圖象中分割出來，本文研究了玻殼圖象的分割方法，包括微分直方圖法、 otsu法、直方圖法，最終選用微分直方圖法來分割圖象。 -
( 2 ) using the method of parameter identification in literature [ 117 - 118 ], selecting gain function : giving the initial value of the parameter observer from the time serial of output variables of the system, the numerical simulation result shows that the parameter observer proposed in this paper can identify the unknown parameters of the system quickly and exactly no matter if the parameters keep invariable or change in some rule, and the identifying speed is faster than the method in [ 117 - 118 ], when the unknown parameters are being identified, vith parameter compensator, it can synchronizes two hyperchaotic systems completely even if some parameters mismatch
（ 2 ）採用文獻[ 117 - 118 ]提出的參數辨識方法，通過選取更一般的增益函數： l _ i （ x _ i ） = kx _ ii = 1 ， 2 ， 3並根據系統輸出變量的時間序列給出參數觀測器的初始值來進行參數辨識，數值模擬結果表明：採用本文的參數觀測器，在系統參數固定或變化的情況下，都可對系統未知參數實現快速高精度辨識，辨識的速度快于文獻[ 117 - 118 ]提出的方法；在辨識參數的同時，結合參數補償器，使兩個參數不匹配的超混沌系統同步。
