- anon_tor_12345 6y agoYes I'm very familiar with this but this is just MISR i.e. purely a software solution (Peyman Milanfar is one of the original researchers associated with MISR). Fortunately elsewhere in this thread hardware implementations have been demonstrated.
- sorenjan 6y agoThere are hardware implementations referenced in the blog post, and in the linked published paper. > In the early 2000s, Farsiu et al. [2006] and Gotoh and Okutomi [2004]formulated superresolution from arbitrary motion as an optimization problem that would be infeasible for interactive rates. Ben-Ezraet al. [2005] created a jitter camera prototype to do super-resolution using controlled subpixel detector shifts. This and other works inspired some commercial cameras (e.g.,Sony A6000,Pentax FF K1,Olympus OM-D E-M1orPanasonic Lumix DC-G9) to adopt multi-frame techniques, using controlled pixel shifting of the physical sensor. However, these approaches require the use of a tripod or a static scene. https://arxiv.org/pdf/1905.03277.pdf https://arxiv.org/pdf/1905.03277.pdf
- anon_tor_12345 6y agodamn the Ben-Ezra paper is exactly what i imagined being the scope of work for my planned dissertation. guess it's a good thing i didn't pursue it lol.
