In this letter, dual tree complex wavelet transform (DTCWT)-based despeckling algorithm is proposed for synthetic aperture radar (SAR) images, using multivariate statistical theory. The DTCWT coefficients in each subband are modeled with a multivariate Cauchy probability density function (pdf) which takes into account the statistical dependency between the… CONTINUE READING
