Wavelet Diffusion for Document Image Denoising

Wavelet Diffusion for Document Image Denoising

Download www.comp.nus.edu.sg

To distinguish image features from high level noises, we propose to exploit the spatial correlations between wavelet coefﬁcients by replacing the thresholding process with a diffusion process. The proposed smoothing method is more robust to noise when applied to highly corrupted document images.
