Paper Abstract

In practice, SAR images are very often disturbed by a correlated speckle noise. Correlation influence on wavelet coefficients is a difficult problem degrading detection and filtering performances dramatically. We establish a simple analytic relation between high order wavelet coefficient moments/cumulants and speckle second order statistics. The proposed solution is shown to improve detection and filtering algorithm performances in the presence of non white speckle noise.
