Abstract: we proposed a new method of the combination of wavelet transformation denoising with High Order Statistics (HOS) filtering method to denose images, this method deals with both preserving edge details and smoothing n oise better. Simulation experimental results indicate that the method gives better visual quality and PSNR gains than applied wavelet transformation denoising method or HOS filter only.

Key words: image denoising, wavelet transformation, higher order statistics 
