TRMM rainfall correction over the Andean Plateau using wavelet multi-resolution analysis

Haline Heidinger, Christian Yarlequé, Adolfo Posadas, Roberto Quiroz

Analysis of Changes in Quality Assessment with Scale

Claire Thomas, Lucien Wald
2006 2006 9th International Conference on Information Fusion  
Our work deals with the assessment of the quality of multimodal images synthesized at a better spatial resolution by the means of another image having such a resolution.  ...  This extrapolation hypothesis is the major limitation of the application of protocols. The validity of this hypothesis is studied for 44 case studies. Several distances are selected.  ...  The degradation in resolution was made by the means of the UWT (undecimated wavelet transform) called "• trous" (with holes) [6] .  ...

Fine-Scale Structures In Saturn'S Rings: Waves, Wakes And Ghosts

Kevin BAILLIE
2011 Zenodo  
The UVIS instrument allowed stellar occultation observations of structures in the rings with the best resolution available (around 10 meters depending on geometry and navigation), bringing our understanding  ...  However, most of our observed structures could not be explained with simple resonances with external satellites and some other mechanism has to be involved.  ...  The image is from above the unilluminated face of the rings with a radial resolution of ∼ 6 km/pixel. The occultation data are shown at 10 km resolution.  ...
