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. 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). Hyperspectral document imaging has shown potential for solving many challenging problems of document image analysis including signature ex traction, ink or document aging, information retrieval. 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. Introduction to hyperspectral image analysis peg shippert, ph. Background the most significant recent breakthrough in remote sensing has been the development of hyperspectral sensors and software to analyze the resulting image data. 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. 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. Learn how to process hyperspectral data with envi just check out the contents of the course below. This step-by-step video tutorial starts from the basic hyperspectral image analysis, goes through the atmospheric corrections and ends with deep vegetation analytics. The hyperspectral image analysis toolbox (hiat) is a collection of algorithms that extend the capability of the matlab numerical computing environment for the processing of hyperspectral and. one such technological advance here is hyperspectral imaging, where cameras capture more than the usual three bands of coloured light found in traditional digital imaging. This review will specifically focus on the subsequent analysis approach known as hyperspectral image analysis.
