  1. This paper introduces the methods of hyperspectral images band selection based on the property of hyperspectral remote sensing images, utilizes the projection pursuit approach to find optimal solutions for a selected projection index based on dynamical evolutionary algorithm and then project a high dimensional data set into a low dimensional data space to produce a sequence of projection images, explores zero - detection method to threshold projection images to detect anomaly tar get

    摘要運用基於波段間相關性的高光譜影像波段選取方法進行波段的預選取,採用投影尋蹤的方法在動力演化演算法的基礎上尋找最佳投影方向,將高維數據投影至低維數據空間,在各投影分量圖像上採用零點檢測閾值化的方法進行異常目標的提取。
  2. In vsam, a collection of items used to sequence and locate one or more data records in a base cluster. each alternate index record contains an alternate key value and one or more pointers. when the alternate index supports a key sequenced data set, each data record ' s prime key value is the pointer. when the alternate index supports an entry sequenced data set, the data record ' s rba value is the pointer

    在虛擬存儲存取方法( vsam )中,用於定序和定位基簇中的一個或多個數據記錄的項的匯集.每個備用索引記錄包含一個備用關鍵字的值和一個或多個指針.當該備用索引支持某個關鍵字順序數據集時,每個數據記錄的主關鍵字值就是這種指針.當該備用索引支持某個輸入順序數據集時,該數據記錄的rba (相對位元組地址)值就是這種指針
