Generalized method for sampling spatially correlated heterogeneous speckled imagery (Q1347542)

Summary: This paper presents a general result for the simulation of correlated heterogeneous targets, which are present in images corrupted by speckle noise. This technique is based on the use of a correlation mask and Gaussian random variables, in order to obtain spatially dependent Gamma deviates. These Gamma random variables, in turn, allow the obtainment of correlated \({\mathcal K}\) deviates with specified correlation structure. The theoretical properties of the procedure are presented, along with the corresponding algorithm.
