The main purpose of this project was to investigate the possibility of using airborne laser scanning data as a source of information for supervised land cover classification of Widawa River vall...
FUZZY IMAGE SEGMENTATION FOR URBAN LAND-COVER CLASSIFICATION
Segmentation classifi cation land-cover image-regions image-objects fuzzy
2015/11/16
In this paper a general fuzzy approach for segmentation-based classification is proposed. Traditional segmentation techniques focus on
partitioning imagery into image-objects with well-deᤙ...
Fusion of High-Resolution Aerial Imagery and LIDAR Data for Object-oriented Urban Land-cover Classification Based on SVM
Aerial imagery Light Detection and Ranging Image Fusion Object-oriented Classification Land-cover Classification Support Vector Machine
2015/10/12
We present a new object-oriented land cover classification method based on Support Vector Machine (SVM) by fusing spectral and
textural information of High-Resolution (HR) aerial imagery and Digital...
THE IDENTIFICATION OF DATA PRIMITIVES TO SEPARATE THE CONCEPTS AND SEMANTICS OF LAND COVER AND LAND USE:THE EXAMPLE OF ‘FOREST’
land use land cover primitives semantics text mining
2015/9/28
This paper is concerned with data and classifications that confuse the concepts of land cover and land use. Conceptual confusion is problematic for data integration and modelling. This has resulted in...
A HYBRID IMAGE CLASSIFICATION APPROACH FOR THE SYSTEMATIC ANALYSIS OF LAND COVER (LC) CHANGES IN THE NIGER DELTA REGION
