Edge-preserving image denoising method using Curvelet transform
LI Shao-fa · Journal of China Institute of Communications · 2004
An image denosing algorithm using Curvelet transform is proposed. We not only adopted an improved Curvelet transform free of 搘arp-around?artifacts, but also combined wavelet thresholding with edge preserving approach to retain the sharpness of the images. Experiments show that our method yields denoised images with higher PSNR value and better visual quality. Key words: image processing; image denoising; Curvelet transform
