REFLECTANCE ESTIMATION FROM URBAN TERRESTRIAL IMAGES: VALIDATION OF A SYMBOLIC RAY-TRACING METHOD ON SYNTHETIC DATA
Radiometry reflectance BRDF ray-tracing terrestrial images
2014/5/8
Terrestrial geolocalized images are nowadays widely used on the Internet, mainly in urban areas, through immersion services such as Google Street View. On the long run, we seek to enhance the visualiz...
Regional-scale geostatistical inverse modeling of North American CO2 fluxes: a synthetic data study
Regional-scale geostatistical North American CO2 fluxes a synthetic data study
2010/8/16
A series of synthetic data experiments is performed to investigate the ability of a regional atmospheric inversion to estimate grid-scale CO2 fluxes during the growing season over North America. The i...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data
basal properties ice streams surface measurements non-linear Bayesian inverse approach
2010/2/4
We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We dem...
