In this paper, a dual-tree complex wavelet transform (DTCWT) based hybrid image denoising algorithm which combines fourth order Partial Diffusion Equation (PDE) and adaptive thresholding is proposed for Gaussian noise corrupted images by considering the significant dependences of the wavelet coefficients across different scales. The DTCWT has the advantage of improved directional selectivity, approximate shift invariance, and perfect reconstruction over the discrete wavelet transform. The… CONTINUE READING
