Paper Abstract

A novel denoising method based on the nonsubsampled wavelet-based contourlet transform (N-WBCT) was proposed in this paper. It employs wavelet transform for multi-scale decomposition, and nonsubsampled directional filter banks (NSDFB) for directional decomposition. N-WBCT has not only the properties of multi-resolution and multi-direction, but also the property of translation invariance, which is useful in eliminating the Gibbs phenomenon. The experiment results showed that this algorithm can get higher PSNR and the better visual.
