SplineSplat: 3D Ray Tracing for Higher-Quality Tomography
Youssef Haouchat, Sepand Kashani, Aleix Boquet-Pujadas +2
We propose a method to efficiently compute tomographic projections of a 3D volume represented by a linear combination of shifted B-splines. To do so, we propose a ray-tracing algor…

A Statistical Benchmark for Diffusion Posterior Sampling Algorithms
Martin Zach, Youssef Haouchat, Michael Unser
We propose a statistical benchmark for diffusion posterior sampling (DPS) algorithms for Bayesian linear inverse problems. The benchmark synthesizes signals from sparse Lévy-proces…

Generalized Ray Tracing with Basis functions for Tomographic Projections
Youssef Haouchat, Sepand Kashani, Philippe Thévenaz +1
This work aims at the precise and efficient computation of the x-ray projection of an image represented by a linear combination of general shifted basis functions that typically ov…
