Abstract
This article addresses the problem of SAR (synthetic aperture radar) images non-coherent change detection. Here, we use a multi-scale registration technique based on mutual information and we introduce a novel preprocessing algorithm to get rid of the corruptive multiplicative noise (also called speckle) on SAR images. The change detection is then easily and accurately performed with a local comparison between pixels.
