The Antarctic ice sheet response to the global climate change, specifically the ice flow speed change of the glaciers, has been investigated by many researchers. However, most research results cover t...
ON THE CHALLENGES IN STEREOGRAMMETRIC FUSION OF SAR AND OPTICAL IMAGERY FOR URBAN AREAS
Data fusion stereogrammetry synthetic aperture radar (SAR) optical imagery multi-sensor matching urban areas
2016/11/24
This paper discusses the challenges arising if SAR and optical imagery shall be fused for stereogrammetric 3D analysis of urban areas. In this context, a concept for SAR and optical data fusion is pre...
SEMI-AUTOMATED FOREST STAND DELINEATION USING WAVELET-BASED SEGMENTATION OF VERY HIGH RESOLUTION OPTICAL IMAGERY IN FLANDERS,BELGIUM
image segmentation forest stand delineation wavelets
2015/8/19
Stand delineation estimation is one of the cornerstones of forest inventory mapping and a key element to forest management decision making. Stands are forest management units defined mainly by similar...
OBJECT BASED FOREST STAND DENSITY ESTIMATION FROM VERY HIGH RESOLUTION OPTICAL IMAGERY USING WAVELET BASED TEXTURE MEASURES
segmentation stand density forest inventory wavelets very high resolution
2015/8/19
Stand density or tree density, expressed as the number of trees per unit area, is an important forest management parameter. It is used by foresters to evaluate regeneration, to assess the effect of fo...
This paper presents a scheme for building detection and building reconstruction from LIDAR data and optical imagery. The
proposed scheme comprises two major parts: (1) detection of building regions, ...
