چکیده:

We propose a new wavelet-based method for image denoising that applies the two dimensions Dual Tree wavelet Transform and adapt thereshold in each local area to obtain better denoised image. Empirical results show that new approach is better than older algorithms. In this paper, the structure of Dual Tree wavelet transform (DTDWT) is modified and Comparison results are also presented.
