Torus computed tomography for experimental data
Ella Salo, Alexander Meaney, Olli Koskela +1
Torus computed tomography (Torus CT) reconstructs the Fourier coefficients of an image from X-ray data along closed geodesics on the flat torus. We extend Torus CT to experimental…

Per-channel autoregressive linear prediction padding in tiled CNN processing of 2D spatial data
Olli Niemitalo, Otto Rosenberg, Nathaniel Narra +2
We present linear prediction as a differentiable padding method. For each channel, a stochastic autoregressive linear model is fitted to the padding input by minimizing its noise t…

Torus computed tomography
Joonas Ilmavirta, Olli Koskela, Jesse Railo
We present a new computed tomography (CT) method for inverting the Radon transform in 2D. The idea relies on the geometry of the flat torus, hence we call the new method Torus CT.…
