A comparison of hyperspectral data and worldview-2 images to detect impervious surface

2012 4th Workshop on Hyperspectral Image and Signal Processing (WHISPERS), 2012
One of the most important issues in urban area study during these years is loss of land resources due to rapid expansion and development of urban centers and cities therefore impervious surface (IS) is increased. Thus detection and mapping the impervious surface accurately is one of the important tasks in urban remote sensing.

Presentation of the Kauth–Thomas transform for WorldView-2 reflectance data

Remote Sensing Letters, 2014
We present the Kauth–Thomas (K-T) transform coefficients for the reflectance data of the WorldView-2 (WV-2) sensor. The K-T transform is a widely used spectral enhancement, which employs a set of eigenvectors that transforms the given spectral space into a defined feature space.

Remote Sensing Image Fusion of Worldview-2 Satellite Data

Applied Mechanics and Materials, 2013
In view of the situation that most image fusion methods make spectral distortion more or less; this paper proposes a spatial projection method by introducing the Gaussian scale space theory. According to mechanism of the human visual system represented by the Gaussian scale space, the spatial details feature information are extracted from the original ...

Building height retrieval from WorldView-2 multi-angular images

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
The paper presents a new algorithm for the estimation of the heights of buildings acquired by multiangular multispec-tral/panchromatic acquisitions. The proposed method aims at exploiting the complete multiangular spatial and spectral information provided by the WorldView-2 system with controlled computational complexity of the overall automated system.

Image patch characterization with shape distributions: Application to WorldView-2 images

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
This paper describes an image patch characterization for image information mining tasks. An image patch is first decomposed into a multi-scale segmentation thanks to the Max Tree representation. Then, each segment is described by shift invariant shape attributes. Finally, the segment attributes are aggregated into a shape distribution which constitutes

Detection of moving vehicles with WorldView-2 satellite data

2012
Traffic monitoring in urban areas is a complex issue and recent Remote Sensing technologies can play an important role in planning and monitoring the urban environment. In this studya semi-automatic object-oriented workflow was designedto detect moving vehicles and their speed from single pass WorldView-2 multispectral data.
