Remote sensing for hyperspectral and multispectral imagery analysis. Asd fieldspec 4 standard-res spectroradiometer asd pioneered the. Figuratively speaking, hyperspectral sensors collect information as a set of images. Each image represents a narrow wavelength range of the electromagnetic spectrum, also known as a spectral band. These images are combined to form a three-dimensional (x,y,) hyperspectral data cube for processing and analysis, where x and y represent two spatial dimensions of the scene, and represents the spectral dimension (comprising a range of wavelengths). The acquisition and collection of hyperspectral data have become much easier and affordable, making hyperspectral image analysis to be one of the promising techniques in many applications including precise agriculture, environmental analysis, military surveillance, mineral exploration, urban investigation, e. This book reviews the cutting edge in algorithmic approaches addressing the challenges to robust hyperspectral image analytics, with a focus on new trends in machine learning and image processingunderstanding, and provides a comprehensive review of the cutting edge in hyperspectral image analysis. Hyperspectral image analysis is aimed at engineers, chemists and other scientists who explore and model hyperspectral image data including development of classification models and predictive models. In the pharmaceutical, food and beverage, and process industries. The hyperspectral image analysis toolbox (hiat) is intended for the analysis of hyperspectral and multispectral data. Hiat is a collection of functions that extend the capabilities of the matlab numerical computing environment. Capturing hyperspectral data, modelling applications with advanced image segmentation and data analysis and running them in real-time is all built-in to our software suite. For the sake of clarity, sections 4 structure of hyperspectral images, 5 general scheme to perform hyperspectral image analysis will be illustrated using a small part of the hyperspectral image presented in fig. Hyperspectral versus multispectral, review some recent applications of hyperspectral image analysis, and summarize image-processing techniques commonly applied to hyperspectral imagery. Spectral image basics to understand the advantages of hyperspectral imagery, it may help to first review some basic spectral remote sensing concepts.
