Image Denoising Algorithm Based on Bilateral Filtering and Dual-Tree Complex Wavelet
An image denoising algorithm based on bilateral filtering and dual-tree complex wavelet transform is proposed.The noisy image is decomposed into multi-scale and multi-directional subbands by dual-tree complex wavelet transform,and each high-pass directional subband is denoised by local Wiener filtering with directional windows.During the reconstruction,each low-pass constructed image is further denoised by the bilateral filtering in spatial domain.The experiment results show that the proposed image denoising algorithm achieves significant improvement of denoising performance.
