Geometry Calibration in Tomography with a Differentiable Ray-Based Model
Youssef Haouchat, Aleix Boquet-Pujadas, Sepand Kashani +2
Geometric misalignments between the nominal and true acquisition parameters in tomography degrade reconstructions. We propose a framework that jointly reconstructs the volume and c…
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…
LenslessPiCam: A Hardware and Software Platform for Lensless Computational Imaging with a Raspberry Pi
Eric Bezzam, Sepand Kashani, Martin Vetterli +1
Lensless imaging seeks to replace/remove the lens in a conventional imaging system. The earliest cameras were in fact lensless, relying on long exposure times to form images on the…
