3D FLOOD INFORMATION FROM SAR AS A MEANS FOR REDUCING UNCERTAINTIES IN FLOOD INUNDATION MODELING
Floods SAR Imagery Cartography Distributed Modeling Calibration Uncertainties
2015/12/26
SAR images of river inundation prove to be very relevant for operational flood management. However, common exploitation of satellite images of floods is generally restricted to a flood extent extracti...
Robust and Automatic Vanishing Points Detection with Their Uncertainties from a Single Uncalibrated Image, by Planes Extraction on the Unit Sphere
Photogrammetry Geometry Vanishing points extraction Image Orientation Error estimation
2015/12/4
This paper deals with the retrieval of vanishing points in uncalibrated images. Many authors did work on that subject in the computer vision field because the vanishing point represents a major inform...
