  • One-dimensional radar interferometry for line infrastructure

    Publication Year: 2009, Page(s):V-9 - V-12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1060 KB) | HTML iconHTML

    Here we present an efficient algorithm to analyze the deformation behavior of line infrastructure, such as water defense structures and railways, using radar interferometric time series. Due to the limited amount of pixels and the consistent reflection properties, a detailed analysis can be performed. By considering neighboring pixels, the influence of a large part of error sources is reduced. How... View full abstract»

  • InSAR permanent scatterers selection using SAR SVA filtering

    Publication Year: 2009, Page(s):V-13 - V-16
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (262 KB) | HTML iconHTML

    Permanent scatterers (PS) approach allows the identification of radar targets not affected by decorrelation noise then suitable for reliable SAR interferometric measurements. This paper introduces a new technique allowing the selection of stable scatterers based on adaptative SVA (Spatially Variant Apodization) filtering. Indeed, SVA filters identify SAR pixels with strong reflectivity (maximum of... View full abstract»

  • Bayesian restoration of interferometric phase through biased anisotropic diffusion

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (466 KB) | HTML iconHTML

    In this paper a new Bayesian algorithm for interferometric phase restoration is presented. Based on a non-linear anisotropic extension of Orientation Diffusions, the inherent directionality of the fringe structure is introduced into its prior model. It also accounts for the periodicity of the phase representation. A fidelity term derived from the anisotropic metrics and the InSAR phase statistics ... View full abstract»

  • A new algorithm for the phase unwrapping of interferogram stacks

    Publication Year: 2009, Page(s):V-21 - V-24
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (397 KB) | HTML iconHTML

    Phase unwrapping is a key step in DInSAR stack analysis: it allows restoring the phase values starting from the restricted ones to extract the deformation time series of the observed area. Most of the available interferogram stack phase unwrapping techniques unwrap each interferogram separately. Based on a strategy proposed in the literature, in this work we discuss an unwrapping procedure that ex... View full abstract»

    A novel GPU based time-domain raw signal simulator for InSAR is proposed in this paper to exploit the parallel computation of GPU using CUDA language. This simulator combines the advantages of both time-domain and frequency-domain InSAR simulator, i.e., it considers the baseline oscillation and real orbit, and it is also very efficient. Experimental results show the effectiveness of the simulator ... View full abstract»

    In this paper different methods for deriving digital surface models (DSM) from ALOS Prism three line stereo images are generated and analyzed. The methods used are classical hierarchical stereo matching with forward intersection and two different dense stereo methods.

  • Matching of high resolution optical data to a shaded DEM

    Publication Year: 2009, Page(s):V-37 - V-40
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (621 KB) | HTML iconHTML

    One of the first essential steps in the analysis of satellite imagery is the orthorectification of the images. Orthorectification without ground control points (GCPs) using only the ephemeris and attitude data provided by the satellite operator provides an absolute accuracy of about 20 m to 1 km (depending on the satellite), which can be improved by measuring precise GCPs. In this paper, a method ... View full abstract»

    The new high-resolution and full polarimetric modes of RADARSAT-2 are evaluated for digital elevation model (DEM) generation using stereo-radargrammetry with Toutin's 3D physical model. The stereo-radargrammetric DEMs were evaluated with accurate Lidar data.

  • Using geometric accuracy of TerraSAR-X data for improvement of direct sensor orientation and ortho-rectification of optical sattelite data

    Publication Year: 2009, Page(s):V-44 - V-47
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (203 KB) | HTML iconHTML

    The very high geometric accuracy of geocoded data of the TerraSAR-X satellite has been shown in several investigations. It is due to the fact that it measures distances which are mainly dependent on the position of the satellite and the terrain height. If the used DEM is of high accuracy, the resulting geocoded data are very precise. This precision can be used to improve the exterior orientation a... View full abstract»

  • Interactive object segmentation in high resolution satellite images

    Publication Year: 2009, Page(s):V-48 - V-51
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (510 KB) | HTML iconHTML

    High resolution remote sensing image segmentation is a great challenge in terms of potential applications, but also because of the difficulty of the task. Fully automatic algorithms are not able to extract all the desired features from complex images but visual image analysis is time consuming and tedious (therefore error prone). In this work we present a simple, yet powerful approach for interact... View full abstract»

    The DEM multi-scale representation, progressive compression and transmission based on integer lifting wavelet can eliminate the redundant data between resolutions for web-based spatial information system. Through experimental data and theoretical analysis, the 2/6 integer wavelet was found to be the most suitable transform for the DEM multi-scale progressive compression among the 14 reversible int...

  • Dynamic tolerance setting method for plane sweep algorithm

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (208 KB) | HTML iconHTML

    In this paper, we analyze the characteristic of floating point numbers computation in scientific computing, and adopt the Gaussian error propagation rule to analyze the computational error. By this method, an appropriate double value (i.e. the dynamic tolerance) is computed in advance and set for the plane sweep algorithm to judge whether two floating point numbers equal. By this method, we can ge... View full abstract»
