A new image denoising method based on Dual-tree complex wavelet combining partial differential equation in image denoising is presented. Image denoising with Wiener filter can not keep the edges of the image well enough due to the lack of directional ability in common tensor wavelet transform. Authors use the complex wavelet which has stronger directional ability and locally 6 directional Wiener filter to get a “clearer image”

then use “clearer image” guidance the diffusion function of partial differential equation to reduce noise in the image.Results of experiment show: the recovered images have higher PSNR and better visual quality than DTCW and PDE.
