Produce feldspar mineral map using Spectral Angle Mapper (SAM) technique by hyperspectral image analysis

نویسندگان

چکیده

The analysis of the hyperspectral image is an important method used in mineral detection. A map Feldspar will produced for study area, which lies to west holy province Karbala and limited that download from USGS website (type EO-1 satellite) , by using Spectral Angle Mapper (SAM) technique Erdas software, based on calculating spectral reflection curve any point feldspar available library software. For purpose verifying results analysis, ground truth ( field work ) was collecting 12 soil samples finding each sample device (ASD) result show match between ground, where map.

Spectral Correlation Mapper (SCM): An Improvement on the Spectral Angle Mapper (SAM)

The classification methods for feature spectra are based on a comparison of the spectral image with a reference spectrum (endmembers or spectral libraries). The comparison is accomplished through a criterion of similarity. The Spectral Angle Mapper SAM is one of the leading classification methods because it evaluates the spectra similarity in order to repress the influence of the shading to acc...

The Tradeoff Analysis for Remote Sensing Image Fusion Using Expanded Spectral Angle Mapper

Image fusion is a useful tool in integrating a high-resolution panchromaticimage (HRPI) with a low-resolution multispectral image (LRMI) to produce a highresolutionmultispectral image (HRMI). To date, many image fusion techniques have beendeveloped to try to improve the spatial resolution of the LRMI to that of the HRPI with itsspectral property reliably preserved. However, many studies have in...

Spectral Angle Mapper (SAM) for anisotropy class indexing in imaging spectrometry data

An empirical (target-) BRDF normalization method has been implemented for Imaging Spectrometry data processing, following the approach of Kennedy, published in 1997. It is a simple, empirical method with the purpose of a rapid technique, based on a least-squares quadratic curve fitting process. The algorithm is calculating correction factors in either multiplicative or additive manner for each ...

Jeffries Matusita-spectral Angle Mapper (jm-sam) Spectral Matching for Species Level Mapping at Bhitarkanika, Muthupet and Pichavaram Mangroves

This paper proposes a novel hyperspectral matching algorithm by integrating the stochastic Jeffries-Matusita measure (JM) and the deterministic Spectral Angle Mapper (SAM), to accurately map the species and the associated landcover types of the mangroves of east coast of India using hyperspectral satellite images. The JM-SAM algorithm signifies the combination of a qualitative distance measure ...

Adaptive affinity propagation with spectral angle mapper for semi-supervised hyperspectral band selection.

Band selection is a commonly used approach for dimensionality reduction in hyperspectral imagery. Affinity propagation (AP), a new clustering algorithm, is addressed in many fields, and it can be used for hyperspectral band selection. However, this algorithm cannot get a fixed number of exemplars during the message-passing procedure, which limits its uses to a great extent. This paper proposes ...
