In this work, we devise a change detection technique for urban areas based on the fusion of temporal series of SAR images with a single multi-band optical image.

The approach has been validated by using a multitemporal set of ENVISAT SAR images and a couple of QuickBird optical images, that are also used to provide evidence on the changes by visual inspection at high resolution.

Abstract
In this work, we devise a change detection technique for urban areas based on the fusion of temporal series of SAR images with a single multi-band optical image. The proposed technique aims at exploiting both the high repetition observation rate available with the new generation of SAR systems and the high level of details available even in a single multiband optical image. The approach has been validated by using a multitemporal set of ENVISAT SAR images and a couple of QuickBird optical images, that are also used to provide evidence on the changes by visual inspection at high resolution. The preliminary results shown in the paper show the potentiality of the joint processing of SAR and optical images. © 2007 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
