A Novel Adaptive Probabilistic Nonlinear Denoising Approach for Enhancing PET Data Sinogram
We propose filtering the PET sinograms with a constraint curvature motion diffusion. The edge-stopping function is computed in terms of edge probability under the assumption of contamination by Poisson noise. We show that the Chi-square is the appropriate prior for finding the edge probability in t...
