  1. 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。
  2. According to the orthogonal wavelet conditions, a two - dimensional adaptive stationary wavelet which matches the fabric texture is constructed by using the average energy ratio between the defect area and defect - free area as optimal objective function

    摘要根據小波正交條件，通過使用疵點圖像的疵點區與無疵點區能量均值比為優化目標函數，構造與織物紋理模式相匹配的二維自適應平穩小波。
  3. Algorithms for defect classification are developed. classifiers are constructed based on back - propagation network. the network configuration bases on input and output

    2 .研究和開發了系統的缺陷分類方法，用bp神經網路構建了系統的分類器。
