GEOLOGICAL MAPPING BY COMBINING SPECTRAL UNMIXING AND CLUSTER ANALYSIS FOR HYPERSPECTRAL DATA
Geology Mineral Unmixing Cluster Analysis Hyperspectral Cuprite
2016/11/30
Spectral unmixing of hyperspectral data often fails to select some minerals and rocks having flat spectra but no diagnostic absorption features as endmembers, even if they are actually important endme...
COMPREHENSIVE SPECTRAL SIGNAL INVESTIGATION OF A LARCH FOREST COMBINING GROUND-AND SATELLITE-BASED MEASUREMENTS
Data Fusion Spectral Signal Field Spectrometry Landsat 8 OLI Classification Larix decidua
2016/11/23
Collecting comprehensive knowledge about spectral signals in areas composed by complex structured objects is a challenging task in remote sensing. In the case of vegetation, shadow effects on reflecta...
A SIMPLE INTERPRETATION OF THE RICE SPECTRAL INDICES SPACE FOR ASSESSMENT OF HEAVY METAL STRESS
Heavy metal stress Hyperspectral data Spectral indices space Visualization Rice
2016/11/23
Heavy metal stress will induce the change of the bio-parameters like chlorophyll, nitrogen and water content of rice. In this paper, we analyzed the traditional spectral index which has strong relatio...
A NOVEL IMAGE FUSION METHOD FOR MULTI-SPECTRAL AND HIGH-RESOLUTION PANCHROMATIC IMAGES
Image Fusion Multi-Source Images Spectral Distortion Spectral Preservation Spatial Resolution SAO
2016/3/17
How to greatly benefit form a variety of remote sensing data has become a bottle-neck problem in application of remote sensing. As an image has high spectral resolution, but relatively lower spatial r...
ADVANCES IN HYPERSPECTRAL AND MULTISPECTRAL IMAGE FUSION AND SPECTRAL UNMIXING
hyperspectral image fusion super-resolution spectral unmixing endmembers processing techniques
2015/9/21
In this work, we jointly process high spectral and high geometric resolution images and exploit their synergies to (a) generate a fused image of high spectral and geometric resolution; and (b) improve...
EXTRACTION OF OPTIMAL SPECTRAL BANDS USING HIERARCHICAL BAND MERGING OUT OF HYPERSPECTRAL DATA
Classification Feature selection Sensor design Hyperspectral Spectral bands Multispectral
2015/9/21
Spectral optimization consists in identifying the most relevant band subset for a specific application. It is a way to reduce hyperspectral data huge dimensionality and can be applied to design specif...
SPECTRAL UNMIXING OF LOW RESOLUTION IMAGES FOR MONITORING SOIL SEALING
Sub-pixel classification Spectral Mixture Analysis Impervious surfaces Endmember selection SPOTVEGETATION
2015/8/3
The expansion of urban areas has a negative impact on the environment. The increase of impervious or sealed surfaces is directly proportional to this expansion. The estimation of sealed surfaces has o...
IMPROVING LINEAR SPECTRAL UNMIXING THROUGH LOCAL ENDMEMBER DETECTION
Hyperspectral Data Set Local Linear Spectral Unmixing (LLSU) Maximum Likelihood Classification (MLC)
2015/4/1
There are a considerable number of mixed pixels in remotely sensed images. Different sub-pixel analyses have been recently developed correspondingly. A well-known method is linear spectral unmixing wh...
