Light Field-Based Underwater 3D Reconstruction Via Angular Resampling. (arXiv:2109.02116v3 [cs.CV] UPDATED)

Recovering 3D geometry of underwater scenes is challenging because of
non-linear refraction of light at the water-air interface caused by the camera
housing. We present a light field-based approach that leverages properties of
angular samples for high-quality underwater 3D reconstruction from a single
viewpoint. Specifically, we resample the light field image to angular patches.
As underwater scenes exhibit weak view-dependent specularity, an angular patch
tends to have uniform intensity when sampled at the correct depth. We thus
impose this angular …
