| Abstract: | A scheme of image denoising based on wavelet transform is proposed in this paper. By thresholding the wavelet transform coefficients of noisy images, the original image can be reconstructed correctly. It is adaptive by combining the information of the image. The experiment result shows that image denoising using this scheme is quite effective. |
