为了利用遥感影像进行更加精确的找矿预测，本文选择新疆东天山尾亚地区ASTER数据进行矿化蚀变信息提取方法研究。为了提高信息提取精度，本文提出了结合主成分分析（PCA）、多尺度分割和支持向量机（SVM）的遥感矿化蚀变信息提取方法。首先，分析ASTER数据的特征，选取各矿化蚀变信息的特征波段，对组合波段进行主成分分析，获得主分量图像；然后，对各主分量图像进行多尺度分割，并获得分割之后的均值图像；接着，提取训练样本，利用SVM对训练样本进行训练，采用试验方法求得最优核参数和松弛变量，构造最优SVM模型；最后，运用最优SVM模型完成矿化蚀变信息的提取。进行主成分分析时，铁染蚀变信息选择Band 1、2、3、4组合，Al-OH基团蚀变信息选择Band 1、4、6、7组合，OH和CO

In order to accurately locate the deposit
the ASTER data of Weiya area in eastern Tianshan Mountain of Xinjiang is selected to study the extraction method of mineralization alteration information. To improve the accuracy of ASTER data mineralization alteration information extraction method
a method based on Principal Component Analysis (PCA)
multilevel segment method
and Support Vector Machine (SVM) is proposed in this study. First
the special band of alteration information is selected after analyzing the ASTER data
and the principal component image is acquired by PCA. Then
the mean image is obtained after the principal component image is segmented. Subsequently
the training samples are trained by SVM after the training samples are extracted. Moreover
the optimal model is constructed using the optimal kernel parameters and flabby variable obtained by repeated testing. Finally
the optimal model is used to accomplish the extraction of alteration information from ASTER data. The abnormal ferric contamination is extracted using 1
