Modern satellites tag their images with geolocation information using GPS and star tracking systems. Depending on the quality of the geopositioning equipment, errors may range from a few meters to tens of meters on the ground. At the current state of art, there is no established method to automatically correct these errors limiting the large-scale joint(More)
High-resolution and accurate Digita (DEM) generation from satellite image problem. In this work, a stereo 3 framework is outlined that is nonstereoscopic satellite image pa captured by different satellites. The o maps given by stereo reconstruction height maps given by a multiview a Probabilistic Volumetric Representat map qualities are measured in compa(More)
This paper generalizes the previously developed automated edge-detection parameter selection algorithm of Yitzhaky and Peli. We generalize the approach to arbitrary multidimensional, continuous or discrete parameter spaces, and feature spaces. This generalization enables use of the parameter selection approach with more general image features, for use in(More)
