Rock type classification using MGM peak-fitting analysis of hyperspectral reflectance spectra (0.35-2.50 um), Sudbury igneous complex, Ontario by Susan M. J. Cook Download PDF EPUB FB2
Spectral reflectance data for the deposit were published by Rowan and others (5). The data consist of 47 bands from to nm in nm intervals each collected at four polarizations. Data preprocessing and most of the subsequent analysis was done using basic procedures from ENVI software (Research Systems, Inc., Boulder, CO).
Abstract. Hyperspectral imaging (HI) is a method of observing and enhancing geological rock properties that are not readily apparent visually. Originally developed for the mining industry, HI uses a combination of short-wave infrared light (SWIR) and long-wave infrared light (LWIR) to create a visual ‘map’ of the minerals on the surface of a core that respond to reflectance principles.

Hyperspectral images are images captured in hundrends of bands of the electromagnetic spectrum. This project is focused at the development of Deep Neural Network for landcover classification in hyperspectral images.
Land-cover classification is the task of assigning to every pixel, a class label that represents the type of land-cover. Hyperspectral sensors record the reflectance from the Earth's surface over the full range of solar wavelengths with high spectral resolution.
The resulting high-dimensional data contain rich. Abstract: Hyperspectral image classification, an astonishing tool to distinguish the land covers in remote sensed hyperspectral images, has been investigated by multiple disciplines such as geoscience, environmental science, mathematics, and computer vision.
Following early machine learning (e.g., support vector machines and neural networks) and feature extraction theories (e.g., principal. Application of Hyperspectral Image Analysis Hyperspectral imagery has been used to detect and map a wide variety of materials having characteristic reflectance spectra.
For example, hyperspectral images have been used by geologists for mineral mapping (Clark et al.,) and to detect soil.
Wavelet analysis, which applies wavelet transforms to reflectance spectra, and broadband modelling, which estimates bitumen content directly from resampled hyperspectral reflectance data, were.
The prototype Hyperspectral Analysis process in TNTmips V provides the specialized, interactive analysis tools that are required to fully exploit the spectral range and spectral resolution provided by hyperspectral datasets. The process allows you to work with two different types of objects: hyperspectral images and spectral libraries.

Method 1: Information Entropy - This method is based on evaluating each band separately using the information entropy measure based on the the probability density function of reflectance values in a hyperspectral band and the number of distinct reflectance values.
The probabilities are estimated by computing a histogram of reflectance values. Spectral Libraries / Reflectance Spectra The next task is to identify the minerals whose reflectance spectra most nearly resemble the image spectra. ENVI includes several spectral libraries. For the purposes of this exercise, you will use the JPL Spectral Library (Groves et al., ) and the USGS Spectral Library (Clarke et al., ).
of red light than soils. Several libraries of reflectance spectra of natural and man-made materials are available for public use. These libraries provide a source of reference spectra that can aid the interpretation of hyperspectral and multispectral images.
ASTER Spectral Library, USGS Spectral Library are some of such spectral libraries. The Hyperspectral Analysis process in TNTmips provides the specialized tools you need to fully exploit the spectral range and spectral resolution of your hyperspectral images.
On-the-fly reflectance calibration and an integrated spectral library make the process easy to use, yet it also includes powerful tools for data reduction, spectral search, and spectral mapping. • Some statistical tools such as statistical filtering and using bi- variety regression analysis were suggested to get reliable results.
37 Summary: • Hyperspectral image analysis can be a very powerful tool for cost effective analysis of minerals, identifying mineral abundances and mapping the geological characteristics of an area.In our approach, we acquire hyperspectral images in the visible light wavelength range when the spatial resolution of such images is required for mineral identification purposes.
This means that we can use relatively cheap and low-noise silicon devices. We are also able to use a UV lamp as a light source rather than a near-IR lamp.
