The estimation of the interferometric vertical wavenumber over sloped terrain is an integral step for many and tomographic synthetic aperture radar (SAR) applications. state art this to calculate angle incidence local slope after geometric corregistration has been performed. In letter, alternative approach estimating proposed that requires only range shifts. This considerably simplifies calcula...

coregistration of optical and radar imageries is a major pre-processing step in many remote sensing applications including change detection and interferometric processing. specially, the coregistration faced more difficulties in radar imageries due to the high noise level and intense spatial-temporal decorrelation. hence, non-automatic coregistration methods are much more time consuming and ine...

RESUME The geometric correction of remote sensing images is a preprocessing step required for most applications and studies. The success of CHRIS/PROBA as scientific mission is producing a large archive of image sets that is continuously growing. Although the geometric correction problem is already solved by means of ground control points (GCP) or image corregistration techniques, these methods...

BACKGROUND Children with focal epilepsy unresponsive to anticonvulsant therapy may become surgical candidates. Inter-ictal SPECT (SPECT-IN) studies demonstrate an area of hypoperfusion within the seizure focus in up to 50% of patients. The goal of this study was to evaluate the usefulness of corregistration of MR and SPECT-IN images for localization of the epileptogenic focus. MATERIAL/METHOD...
