商品描述

This book provides information about different types of dimensionality reduction (DR) methods and their effectiveness in hyperspectral data processing. The authors first explain how hyperspectral imagery (HSI) plays an important role in remote sensing due to its high spectral resolution that enables better identification of different materials on the earth's surface. The authors go on to describe potential challenges due to HSI being acquired in hundreds of narrow and contiguous bands, represented as a 3-dimensional image cube, often causing the bands to contain information redundancy. They then show how processing a large number of bands adds challenges in terms of computation complexity that reduces efficiency. The authors then present how DR is an essential step in hyperspectral data analysis to solve these issues. Overall, the book helps readers understand the DR processes and its impact in effective HSI analysis.

本書提供有關不同類型的降維（Dimensionality Reduction, DR）方法及其在高光譜數據處理中的有效性的信息。作者首先解釋了高光譜影像（Hyperspectral Imagery, HSI）在遙感中的重要角色，因為其高光譜解析度使得能夠更好地識別地球表面不同的材料。接著，作者描述了由於HSI是以數百個狹窄且相連的波段獲取的，這些波段被表示為三維影像立方體，常常導致波段中包含信息冗餘的潛在挑戰。然後，他們展示了處理大量波段所帶來的計算複雜性挑戰，這降低了效率。接下來，作者提出降維是高光譜數據分析中解決這些問題的必要步驟。總體而言，本書幫助讀者理解降維過程及其在有效的高光譜影像分析中的影響。
