- W2368487520 abstract "The edge information of image used to be destroyed while denoising.A new method of image denoising using contourlet transform is proposed to maintain more image's edge information.In this way,the edge of image was detected with LOG operator firstly.Then,the image edge and non-edge character in Contourlet coefficients were dealt with an optimal soft thresholding algorithm through selecting different denoising thresholding.Experiment results show that,compared with the commonly-used Donoho soft thresholding Contourlet transform denoising method,this method can get better results in image denoising and keep image's edge information more effectively." @default.
