Abstract

Clouds have a nonstationary nature in that their local spectrum changes with position. We model this nonstationarity by extending the classical 1/f^γ type spectrum. We make γ a function of position and we show that with this choice we can generate nonstationary clouds. Our model can be used to improve denoising algorithms.
