Stochastic analysis of speckle in backscattering

摘要

In this paper, we propose a new approach of the speckle statistics in backscattering imagery. Applicate the Brownian motion theory to the speckle permit us to extract stochastic parameters to characterize it. It seems more powerful than the classical frequential approach to characterize and classify speckle. We present an test application of this method on a human skin.
