| 中文摘要 | wavelet transform is widely used and has good effect on image denoising. wavelet transform has unique advantages in dealing with the smooth area of image but is not so perfect in high frequency areas such as the edges. however, curvelet transform can supply this gap when dealing with the high frequency areas because of the characteristic of anisotropy. in this paper, we proposed a new method which is based on the combination of wavelet transform and curvelet transform. firstly, we detected the edges of the noisy-image using wavelet transform. based on the edges we divided the image into two parts: the smoothness and the edges. then, we used different transform methods to dispose different areas of the image, wavelet threshold denoising is used in smoothness while fdct denoising is used in edges. experimental results showed that we could get better visual effect and higher psnr, which indicated that the proposed method is better than using wavelet transform or curvelet transform respectively. |
