最佳似合曲線-
The variable bandwidth local linear regression method we used in this paper have the advantages of both the local linear regression method and the variable bandwidth idea. the variable bandwidth henced the flexibility of the estimation. and it make this method can fit the spacial complex curve very well. and the asymptotic results of the estimation found the theoretic base for find the best variable bandwidth and drive the pratical best variable bandwidth from data directly
本文所用的變窗寬局部線性回歸方法,繼承了局部線性回歸的優點,並且使用變窗寬提高了所得估計的可塑性。並使之能成功地處理空間非齊次曲線等復雜形狀的曲線擬合問題。所得估計的漸近結果為求漸近最優窗寬方案以及直接從數據估計最優變窗寬提供了理論基礎。 -
This paper selects representative samples wuliangsu lake, yellow river, dongjuyan lake and ejina salina, after information is analyzed, using optimal band index oif index, spectrum characteristics curve and application scope of each band to select optimal bands. the result shows that band 3, 4, 5 are best ones and etm453 combination is the best after r, g, b composed. all this fit for western inner mongolia
根據西部區主要濕地類型本文選取烏梁素海、黃河、東居延海、額濟納鹽沼典型樣地,通過多光譜信息的統計分析,採用波段選取最佳指數oif指數並結合地物光譜特徵曲線、各波段主要用途進行最佳波段的選取,結果一致表明3 、 4 、 5波段是各典型濕地的最佳波段,可作為反映內蒙古西部濕地信息的最佳波段。
