Denoising Technique Using Double Density Dual Tree DWT for Medical Images

Abstract

Even with several techniques or algorithms for denoising implemented, image denoising remains a difficult subject for academics. The implementation of the picture denoising algorithm utilising Double Density Dual Tree Wavelet Transforms is covered in this paper, along with a discussion of critical sampling (Discrete Wavelet) and over complete sampling (Double Density Wavelet) based wavelet transforms. The picture denoising results lead to a few key conclusions, including the fact that complicated wavelet transforms do not always outperform real discrete wavelet transforms and that it is not always true that more redundancy equals higher image denoising performance.
