Resumen:
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 K deviates with specified correlation structure. The theoretical properties of the procedure are presented, along with the corresponding algorithm.
