INFORMATION CONTENT ANALYSIS FROM VERY HIGH RESOLUTION OPTICAL SPACE IMAGERY FOR UPDATING SPATIAL DATABASE
Information Content Topographing Mapping GIS Remote Sensing VHR Images
2018/11/9
High resolution satellite images started with IKONOS imagery. After the launch of the very high resolution IKONOS in the 1990s, a new generation of commercial Earth-imaging satellites have pioneered a...
HYPERSPECTRAL IMAGE DENOISING USING A NONLOCAL SPECTRAL SPATIAL PRINCIPAL COMPONENT ANALYSIS
Hyperspectral Images Noise Reduction Nonlocal Similarity Spectral Spatial Information Principal Component Analysis
2018/5/14
Hyperspectral images (HSIs) denoising is a critical research area in image processing duo to its importance in improving the quality of HSIs, which has a negative impact on object detection and classi...
SPATIAL AND TEMPORAL CHANGES OF AEROSOL OPTICAL DEPTH AND ITS DRIVING FACTORS BASED ON MODIS IN JIANGSU PROVINCE
AOD MODIS Temporal Change Spatial Autocorrelation Gravity Model Driving Factor
2018/5/14
Aerosol Optical Depth (AOD) is of great value for studying air mass and its changes. In this paper, we studied the spatial-temporal changes of AOD and its driving factors based on spatial autocorrelat...
OBJECT-ORIENTED CHANGE DETECTION OF RIPARIAN ENVIRONMENTS FROM HIGH SPATIAL RESOLUTION MULTI-SPECTRAL IMAGES
Object-Oriented Change Detection Definiens Developer Rule Sets Riparian Zones
2015/11/16
The objectives of this research were to: (1) develop rule sets in Definiens Developer 7® for mapping and monitoring riparian zone
land-cover classes within two QuickBird images; and (2) compare...
IMAGE CLASSIFICATION WITH A REGION BASED APPROACH IN HIGH SPATIAL RESOLUTION IMAGERY
Image segments classification object-oriented approach
2015/6/1
A number of studies have been carried out to find an appropriate spatial resolution to which to aggregate data in order
to reduce the variation within an object, and minimize the classification erro...
THE GEOSPECTRAL CAMERA: A COMPACT AND GEOMETRICALLY PRECISE HYPERSPECTRAL AND HIGH SPATIAL RESOLUTION IMAGER
Hyper spectral multispectral georeferencing multiresolution camera
2014/4/24
Small unmanned aerial vehicles are increasingly being employed for environmental monitoring at local scale, which drives the demand for compact and lightweight spectral imagers. This paper describes t...
Spectral spatial coherence of high-power multi-chip LEDs
Spectral spatial coherence high-power multi-chip LEDs
2013/7/3
We investigate the spatial coherence of the light generated from high-power multi-chip red LEDs by using the van Cittert-Zernike theorem. It is theoretically demonstrated that the light generated from...
Dynamics of optomechanical spatial solitons in dual-nanoweb structures
Dynamics of optomechanical spatial solitons dual-nanoweb structures Optics
2012/4/20
We theoretically investigate the stability and dynamics of self-channelled beams that form via nonlocal optomechanical interactions in dual-nanoweb microstructured fibers. These "optomechanicons" repr...
4Pi focusing of spatial ly modula ted radially polarized vorte x beams
4 Pifocusing spatially modulated radially polarized vortex beams
2013/7/3
We propose a method for generating focal beams with special intensity distributions using radially polarized vortex beams in a 4Pi configuration. A spherical dark-hollow beam and hollow beam array can...
Generation of isolated attosecond pulses in the far field by spatial filtering with an intense few-cycle mid-infrared laser
isolated attosecond pulses the far field intense few-cycle mid-infrared laser
2011/8/5
Abstract: We report theoretical calculations of high-order harmonic generation (HHG) of Xe with the inclusion of multi-electron effects and macroscopic propagation of the fundamental and harmonic fiel...

Spatial Variability of Shortwave Irradiance for Snowmelt in Forests
Shortwave Irradiance Snowmelt in Forests
2014/4/3
The spatial variation of melt energy can influence snow cover depletion rates and in turn be influenced
by the spatial variability of shortwave irradiance to snow. The spatial variability of shortwav...
