A change detection measure based on a likelihood ratio and statistical properties of SAR intensity images
TL;DR: The histogram of this change detection measure deduced from the likelihood ratio has a single and steep peak that can be used to reliably and easily determine the change detection threshold.

Blind Speckle Decorrelation for SAR Image Despeckling
TL;DR: The experimental results show that the despeckling filters achieve better performance when they are preceded by the proposed whitening method; furthermore, the radiometric characteristics of the image are preserved.
