Pane , select a rule to configure . for example , select extract attribute value 在“選擇規則”窗格中選擇一個規則,如“提取屬性值” 。
The main steps are extracting and analyzing different types of attributes , preprocessing the extracted attributes , rejecting attribute anomalous values and filtering , seeking and selecting the sensitive attributes combined with drilling and oil extraction data , descending the optimal seismic attributes through k - l changes , and using the synthetic analysis technology with linearity and nonlinearity on reservoir prediction 其主要步驟為:不同種類的屬性提取和分析;屬性的預處理,即剔除異常值并進行濾波等處理;結合鉆井、采油資料尋找和篩選敏感屬性;利用k - l變換來對優選出的地震屬性進行降維處理;利用線性、非線性等綜合分析技術進行儲層預測。
In order to put attributed scattering center " into sar atr use , the method of attributed scattering center extraction is studied in chapter 3 . and the rd ( region decoupled ) - aml ( approximate maximum likelihood ) - clean method is presented for extracting attributed scattering center from sar image , it can extract scattering center from sar image quickly and automatically 為了將屬性散射中心特征用于sar目標分類,第三章研究了sar圖像目標屬性散射中心特征提取方法,提出了rd - aml - cleansar圖像目標屬性散射中心特征提取方法,該方法可由輸入sar圖像快速、自動地提取目標的屬性散射中心特征。
