Adaptive Hybrid Bivariate Double Density Discrete and Complex Wavelet for Image Denoising

Image denoising is an important step in eliminating any noise impact image transmission process. Recently we presented two approaches for Bivariate based denoising. They were Double Density Discrete Wavelet Transform (DD DWT) and Dual Tree Complex CWT). In both techniques decomposed noisy images with either DD DWT or CWT decompositions then applied the technique removal. this paper propose adaptive hybrid that on synthesis of DD-DWT bands DD-CWT but different weights, to deliver enhanced features less especially around edges, which most effected by channels. This proposed has been also edge sharpening Eigen analysis, as separate stages. Simulation result comparisons have performed between band primary DD-DWT, DD- CWT, well other superior literature such original bivariate decompositions. work specific compares decompositions, proposes new filter design suits each them a will be shown.
