Adaptive Graph-based Total Variation for Tomographic Reconstructions
Faisal Mahmood, Nauman Shahid, Ulf Skoglund +1
Sparsity exploiting image reconstruction (SER) methods have been extensively used with Total Variation (TV) regularization for tomographic reconstructions. Local TV methods fail to…
2D Discrete Fourier Transform with Simultaneous Edge Artifact Removal for Real-Time Applications
Faisal Mahmood, Märt Toots, Lars-Göran Öfverstedt +1
Two-Dimensional (2D) Discrete Fourier Transform (DFT) is a basic and computationally intensive algorithm, with a vast variety of applications. 2D images are, in general, non-period…
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…
