ComForWaRD: Complex Fourier-Wavelet Regularized Deconvolution in Computerized Tomography


The inversion of the Radon transform in the presence of noise is numerically unstable in tomographic image reconstruction and is said to be ill conditioned. We propose an efficient hybrid Complex Fourier-Wavelet Regularization (ComForWaRD) that comprises blurring operator inversion followed by noise suppression via scalar shrinkage in both Fourier and… (More)
