Multiscale Super Resolution without Image Priors
Daniel Fu, Gabby Litterio, Pedro Felzenszwalb +1
We address the ambiguities in the super-resolution problem under translation. We demonstrate that combinations of low-resolution images at different scales can be used to make the…

Super-Resolution with Structured Motion
Gabby Litterio, Juan-David Lizarazo-Ferro, Pedro Felzenszwalb +1
We consider the limits of super-resolution using imaging constraints. Due to various theoretical and practical limitations, reconstruction-based methods have been largely restricte…

Deconvolution with a Box
Pedro Felzenszwalb
Deconvolution with a box (square wave) is a key operation for super-resolution with pixel-shift cameras. In general convolution with a box is not invertible. However, we can obtain…
