VOXEL BASED REPRESENTATION OF FULL-WAVEFORM AIRBORNE LASER SCANNER DATA FOR FORESTRY APPLICATIONS
Full-waveform airborne laser scanning Voxel space Ray tracing Forest Filtering
2016/11/30
The advantages of using airborne full-waveform laser scanner data in forest applications, e.g. for the description of the vertical vegetation structure or accurate biomass estimation, have been emphas...
USING MORPHLET-BASED IMAGE REPRESENTATION FOR OBJECT DETECTION
Mathematical morphology object detection Wavelets Wavelet analysis object segmentation
2016/7/28
In this paper, we propose an original method for objects detection based on a special tree-structured image representation – the trees of morphlets. The method provides robust detection of various typ...
ORGANIZATION AND REPRESENTATION OF OBJECTS IN MULTI-SOURCE REMOTE SENSING IMAGE CLASSIFICATION
Object-oriented data model Dynamic object representation Multisensor Geometric feature Spectral feature
2015/12/31
Compared with the traditional remote sensing image processing system based on pixel, there are some unique characters in the object-based classification: various operations on objects; variety of obje...
NEW QUALITY REPRESENTATION FOR HYPERSPECTRAL IMAGES
Hyperspectral quality criteria evaluation compression
2015/12/31
Assessing the quality of a hyperspectral image is a difficult task. However, this assessment is required at different levels of the instrument design: evaluation of the signal to noise ratio necessary...
A 4D MORPHOLOGICAL SCALE SPACE REPRESENTATION FOR HYPERSPECTRAL IMAGERY
Imaging spectrometry Mathematical morphology Anisotropic diffusion Image simplification Levelings Denoising
2015/12/30
In this paper, a 4D scale space representation is introduced aiming at denoising, smoothing and simplifying effectively airborne and spaceborne hyperspectral imagery. Our approach is based on a novel ...

Tweets location Topic modeling Author topic model Twitter
2015/9/21
Social Networks became a major actor in information propagation. Using the Twitter popular platform, mobile users post or relay messages from different locations. The tweet content, meaning and locati...
LOCALLY REFINED SPLINES REPRESENTATION FOR GEOSPATIAL BIG DATA
Big data smooth shape splines local refinement elevation model
2015/9/21
When viewed from distance, large parts of the topography of landmasses and the bathymetry of the sea and ocean floor can be regarded as a smooth background with local features. Consequently a digital ...
MULTISCALE LANDSCAPE REPRESENTATION DERIVED FROM REMOTE SENSING IMAGES USING SPATIAL SUBPIXEL MODELS AND COMBINATORIAL MAPS
landscapes multiscale subpixel graphs combinatorial maps
2015/8/19
Landscapes can be modelled as sets of homogeneous objects (landscape elements) forming areas of characteristic patterns (landscape units).The common way to represent landscapes is by vector GIS data s...
SUPERVISED AND FOREST TYPE-SPECIFIC MULTI-SCALE SEGMENTATION FOR A ONE-LEVEL-REPRESENTATION OF SINGLE TREES
Segmentation LiDAR object-based laser scanning crown delineation region growing OLR region-specific segmentation
2015/8/19
In this paper a supervised approach for the object building / segmentation process utilizing a priori knowledge about the specific scale domain of the target features is proposed. One premise was that...
SEMANTIC DATA INTEGRATION IN A MULTIPLE REPRESENTATION ENVIRONMENT
Semantic data integration Multi Representation Database Generalisation ontologies machine ontology
2015/8/17
Traditionally National Mapping Agencies (NMAs) produce maps at different scales. Since automatic generalisation is not yet possible (it will at least take years) NMAs have to maintain their data sets ...
CLASSIFICATION AND REPRESENTATION OF CHANGE IN SPATIAL DATABASE FOR INCREMENTAL DATA TRANSFER
incremental data transfer change Geographical Object update Classification representation
2015/6/1
Nowadays, more and more spatial databases are used in various fields, so the demands for keeping spatial database “fresh” are growing rapidly. Generally, the end-users get the basic spatial data from ...
