Image denoising based on wedgelet transform and dual-tree complex wavelet transform (WDT-CWT) is proposed in this paper. Wedgelet transform is a new method that has a good performance in approximating edges. The limitation of wedgelet transform is that it smoothes the flat region excessively, leading to the loss of some texture features. To reduce this limitation, we employed dual-tree complex wavelet...
Wavelet transform has been widely used in image fusion; it can well represent smooth regions and regular textures. However, wavelet is unable to provide a good representation of 2D edges. Wedgelet transform has good performance in approximation to edges. In this paper, we propose a new fusion method; it makes good approximation to edges in original images by using wedgelet and retains texture features...
