ESTIMATION OF MONTHLY NEAR SURFACE AIR TEMPERATURE USING GEOGRAPHICALLY WEIGHTED REGRESSION IN CHINA
Near Surface Air Temperature Land Surface Temperature Geographically Weighted Regression MODIS Remote Sensing, Geographically Information System
2018/5/15
Near surface air temperature (NSAT) is a primary descriptor of terrestrial environment conditions. The availability of NSAT with high spatial resolution is deemed necessary for several applications su...
A WEIGHTED CLOSED-FORM SOLUTION FOR RGB-D DATA REGISTRATION
RGB-D data dual-number quaternions registration loop closing globally consistent maps
2016/7/27
Existing 3D indoor mapping of RGB-D data are prominently point-based and feature-based methods. In most cases iterative closest point (ICP) and its variants are generally used for pairwise registratio...
WEIGHTED PYRAMID LINKING FOR SEGMENTATION OF FULLY-POLARIMETRIC SAR DATA
SAR Segmentation Polarization Algorithms Multiresolution Spatial
2015/12/30
Image segmentation has the general goal to define regions within an image, in which all pixels have similiar properties. For fully-polarimetric SAR data this is often done by spectral classification w...
This paper extends kernel weighted GMM estimators recently proposed by the author in
the context of homoskedastic processes to a class of models with conditionally heteroskedastic
innovations. GMM e...
Evaluating trends in spatial relationship between noaa/avhrr-ndvi and rainfall as computed by geographically weighted regression: a case study from a dry region in the middle Kazachstan
NDVI vegetation condition time-trend geographically weighted regression (GWR) modelling
2015/8/21
The spatial relationship between vegetation patterns and rainfall as well as its trend over the period 1985-2000 in the shrubland,
grassland, and cropland of the Middle Kazakhstan was investigated wi...
Weighted combination of multiple classifiers for the classification of hyperspectral images using a genetic algorithm
hyperspectral classification multiple classifiers,
2015/8/20
The improved spectral resolution of modern hyperspectral sensors provides effective means for discrimination of subtly
different classes and objects. However, in order to obtain statistically reliabl...

Airborne synthetic aperture radar Built-up areas Feature weighted fusion Gray symbiotic matrix Variogram
2015/7/27
Synthetic aperture radar in the application of remote sensing technology is becoming more and more widely because of its all-time and all-weather operation, feature extraction research in high resolut...
Object-oriented change detection based on weighted polarimetric scattering differences on POLSAR images
Object-oriented change detection Polarimetric scattering difference Polarimetric synthetic aperture radar
2015/7/27
For wide application of change detection with SAR imagery, current processing technologies and methods are mostly based on pixels. It is difficult for pixel-based technologies to utilize spatial chara...
WEIGHTED GEOMETRIC OBJECT CONSTRAINTS INTEGRATED IN A LINE-PHOTOGRAMMETRIC BUNDLE ADJUSTMENT
line photogrammetry object reconstruction geometric constraints weighting mathematical model adjustment accuracy architecture
2015/1/6
The line-photogrammetric bundle adjustment is a new approach for the 3D reconstruction of polyhedral objects, with several advantages. Observing lines instead of points and integration of additional o...
