Neuronal assemblies within the nervous system produce electrical activity that can be recorded in terms of action potential patterns. Such patterns provide a sensitive endpoint to detect effects of a variety of chemical and physical perturbations. They are a function of synaptic changes and do not necessarily involve structural alterations. In vitro(More)
High resolution stereo satellite imagery is well suited for the creation of digital surface models (DSM). A system for highly automated and operational DSM and orthoimage generation based on CARTOSAT-1 imagery is presented, with emphasis on fully automated georeferencing. The proposed system processes level-1 stereo scenes using the rational polynomial(More)
The Working Group 4 of Commission I on " Geometric and Radiometric Modelling of Optical Spaceborne Sensors " will provide on its website several stereo data sets from high and very high resolution spaceborne stereo sensors. Among these are data from the 2.5 meter class like ALOS-PRISM and Cartosat-1 as well as, in near future, data from the highest(More)
The Remote Sensing Technology Institute (IMF) of the German Aerospace Center (DLR) has more than 20 years of history in developing spaceborne stereo scanners and the corresponding stereo evaluation software systems. It takes part in the CARTOSAT-1 Scientific Assessment Program (C-SAP) as a principal investigator for German (Southeast Bavaria) and Spanish(More)
In this article we propose a method for combining geometric and real-aperture methods for monocular 3D reconstruction of static scenes at absolute scale. Our algorithm relies on a sequence of images of the object acquired by a monocular camera of fixed focal setting from different viewpoints. Object features are tracked over a range of distances from the(More)
In this paper, we will derive a phenomenological model of the bidirectional reflectance distribution function of non-LAMBERTIAN metallic materials typically used in industrial inspection. We will show, how the model can be fitted to measured reflectance values and how the fitted model can be used to determine a suitable illumination position. Together with(More)
An image-based 3D surface reconstruction method based on simultaneous evaluation of intensity and polarisation features (shape from photopolarimetric reflectance) and its combination with absolute depth data is introduced in this article. The proposed technique is based on the analysis of single or multiple intensity and polarisation images. To compute the(More)
This paper addresses a quality assessment of TanDEM-X standard raw DEMs, with a resolution of 12 meters, for two different terrain configurations: urban areas and moderate topography. The analysis is performed in the geospatial domain. Beside TanDEM-X, the same analysis is also carried out for CartoSAT-1 and LiDAR DEMs. The latter one is used as a(More)
An image-based 3D surface reconstruction technique based on simultaneous evaluation of reflectance and polarisation features is introduced in this paper. The proposed technique is suitable for single and multi-image (photopolarimetric stereo) analysis. It is especially suited for the difficult task of 3D reconstruction of rough metallic surfaces with(More)
