NettetUnderwater Image Dehazing with a Light Field Camera Katherine A. Skinner and Matthew Johnson-Roberson University of Michigan, Ann Arbor {kskin, mattjr}@umich.edu Abstract Underwater vision is subject to effects of underwater light propagation that act to absorb, scatter, and attenu-ate light rays between the scene and the imaging platform. NettetW e present a system for capturing, reconstructing, compressing, and rendering high quality immersive light field video. We record immersive light fields using a custom array of 46 time-synchronized cameras distributed on the surface of a hemispherical, 92cm diameter dome.

This … NettetFlat-field correction (FFC) is a technique used to improve quality in digital imaging. It cancels the effects of image artifacts caused by variations in the pixel-to-pixel sensitivity of the detector and by distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes. NettetLightfield Camera. Cameras sample a small portion of the plenoptic function. With the advent of the light-field camera, we can now capture more degrees of the plenoptic function across space.
