Graph Based Sinogram Denoising for Tomographic Reconstructions
Faisal Mahmood, Nauman Shahid, Pierre Vandergheynst +1
Limited data and low dose constraints are common problems in a variety of tomographic reconstruction paradigms which lead to noisy and incomplete data. Over the past few years sino…
