SUMMARY:Learned Large Field-of-View Imaging With Thin-Plate Optics
DESCRIPTION:Technical Papers\n\nLearned Large Field-of-View Imaging With T
 hin-Plate Optics\n\nPENG, SUN, DUN, WETZSTEIN, HEIDRICH...\n\nTypical came
 ra optics consist of a system of individual elements that are designed to 
 compensate for the aberrations of a single lens. \nRecent computational ca
 meras shift some of this correction task from the optics to post-capture p
 rocessing, reducing the imaging optics to only a few optical elements. \nH
 owever, these systems only achieve reasonable image quality by limiting th
 e field of view (FOV) to a few degrees -- effectively ignoring severe off-
 axis aberrations with blur sizes of multiple hundred pixels.\n\nIn this pa
 per, we propose a lens design and learned reconstruction architecture that
  lift this limitation and provide an order of magnitude increase in field 
 of view using only a single thin-plate lens element. Specifically, we desi
 gn a lens to produce spatially shift-invariant point spread functions, ove
 r the full FOV, that are tailored to the proposed reconstruction architect
 ure. We achieve this with a mixture PSF, consisting of a peak and and a lo
 w-pass component, which provides residual contrast instead of a small spot
  size as in traditional lens designs. To perform the reconstruction, we tr
 ain a deep network on captured data from a display lab setup, eliminating 
 the need for manual acquisition of training data in the field.\nWe assess 
 the proposed method in simulation and experimentally with a prototype came
 ra system. We compare our system against existing single-element designs, 
 including an aspherical lens and a pinhole, and we compare against a compl
 ex multi-element lens,} validating high-quality large field-of-view (i.e. 
 53◦) imaging performance using only a single thin-plate element.\n\n
