Total variation projection with first order schemes
This article proposes a new algorithm to compute the projection on the set of images whose total variation is bounded by a constant. The projection is computed through a dual form...

True Multi-Image Alignment and its Application to Mosaicing and Lens Distortion Correction
Multiple images of a scene are related through 20/3D view transformations and linear and non-linear camera transformations. In all the traditional techniques to compute these tran...

A fast back-projection algorithm for bistatic SAR imaging
Using a far-field model, bistatic synthetic aperture radar (SAR) acquires Fourier data on a rather unusual, non-Cartesian grid in the Fourier domain. Previous image formation algo...

Fourier-Based Forward and Back-Projectors in Iterative Fan-Beam Tomographic Image Reconstruction
Fourier-based forward and back-projection methods have the potential to reduce computation demands in iterative tomographic image reconstruction. Interpolation errors are a limita...

Veritas: Combining Expert Opinions without Labeled Data
We consider a variation of the problem of combining expert opinions for the situation in which there is no ground truth to use for training. Even though we don’t have labeled da...
