MULTISCALE DOCUMENTATION AND MONITORING OF L’AQUILA HISTORICAL CENTRE USING UAV PHOTOGRAMMETRY
Documentation Geomatics Historical Centre Photogrammetry UAV
2017/6/20
Nowadays geomatic techniques can guarantee not only a precise and accurate survey for the documentation of our historical heritage but also a solution to monitor its behaviour over time after, for exa...
MULTISCALE SEGMENTATION OF POLARIMETRIC SAR IMAGE BASED ON SRM SUPERPIXELS
synthetic aperture radar (SAR) polarimetric SAR (PolSAR) segmentation multiscale superpixel binary partition tree (BPT) statistical region merging (SRM)
2016/11/23
Multi-scale segmentation of remote sensing image is more systematic and more convenient for the object-oriented image analysis compared to single-scale segmentation. However, the existing pixel-based ...
TOPIC MODELLING FOR OBJECT-BASED CLASSIFICATION OF VHR SATELLITE IMAGES BASED ON MULTISCALE SEGMENTATIONS
Topic modelling Image classification Object-based Multiscale segmentation
2016/11/23
Multiscale segmentation is a key prerequisite step for object-based classification methods. However, it is often not possible to determine a sole optimal scale for the image to be classified because i...
AD HOC MODEL GENERATION USING MULTISCALE LIDAR DATA FROM A GEOSPATIAL DATABASE
LIDAR Database Model Mapping Visualization Urban
2015/9/21
Due to the spread of economically priced laser scanning technology nowadays, especially in the field of topographic surveying and mapping, ever-growing amounts of data need to be handled. Depending on...
MULTISCALE GEOGRAPHIC INFORMATION WITH MULTIGRAPH OF MULTIGRAPHS
Multigraph Hierarchization Peculiarity Graph of Graphs Preciseness Multiscale Information
2015/8/31
Multiscale resolution database MRDB include not only several levels of details (ie preciseness), but also several layers of
peculiarity. The data preciseness means the variable levels of details for...
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...
Multipolarimetric SAR image change detection based on multiscale feature-level fusion
Multipolarimetric SAR Change Detection NSCT Fusion
2015/7/27
Many methodologies of change detection have been discussed in the literature, but most of them are tested on only optical images or traditional synthetic-aperture radar (SAR) images. Few studies have ...
A spatial outlier is a spatial referenced object whose non-spatial attribute values are significantly different from those of other
spatially referenced objects in its spatial neighborhood. It repres...
INTEGRATED AND MULTISCALE SPATIAL DATA TO BASE A GIS FOR THE ANCIENT CITY OF HIERAPOLIS IN PHRYGIA
Archaeological GIS Cultural heritage Cartography Digital Photogrammetry Databases Digital images
2015/5/25
Many historycal, architectural and archaelogical studies pointed on ruins and excavations of the ancient city of Hierapolis, had provided building plans that have been recently collected in a urban ma...
HIERARCHICAL OBJECT REPRESENTATION – COMPARATIVE MULTISCALE MAPPING OF ANTHROPOGENIC AND NATURAL FEATURES
Object-related modelling hierarchical representation
2015/5/18
Hierarchical feature representation through multi-scale segmentation offers new possibilities in mapping complex
systems. We lay out that the recognition of natural features is more difficult than t...

OBJECT-ORIENTED IMAGE ANALYSIS AND SCALE-SPACE: THEORY AND METHODS FOR MODELING AND EVALUATING MULTISCALE LANDSCAPE STRUCTURE
Object-oriented image analysis multiscale landscape structure
2015/3/6
Landscapes are Complex Systems, which by their very nature necessitate a multiscale approach in their monitoring, modeling and management. To assess such broad extents, remote sensing technology is th...
MULTISCALE HAAR TRANSFORM FOR BLUR ESTIMATION FROM A SET OF IMAGES
Sharpness Haar transform multiscale calibration
2014/5/8
This paper proposes a method to estimate the local sharpness of an optical system through the wavelet-based analysis of a large set of images it acquired. Assuming a space-invariant distribution of im...
