Description: The statistics of imagewavelet coefficients is non2Gaussian and can be described by generalized Gaussian
distribution (GGD). The paper investigates the issues of GGD statisticalmodel for wavelet coefficients in a sub2
band and the corresponding parameters estimation . A Bayesian estimate based subband adaptive thresholding de2
noising algorithm is designed, and the performance of noise reduction of this algorithm, compared with other clas2
sicalwavelet thresholding denoising methods, is discussed according to simulation results .
