Abstract

In contrast to traditional binocular or multi-view stereo approaches, the adequately sampled space of observations in light-fifield imaging allows, to obtain dense and high quality depth maps. It also extends capabilities beyond those of traditional methods. Previously, constant intensity has been assumed for estimating disparity of orientation in most approaches to analyze epipolar plane images (EPIs). Here, we introduce a modifified structure tensor approach which improves depth estimation. This extension also includes a model of non-constant intensity on EPI manifolds. We derive an approach to estimate high quality depth maps in luminance-gradient light fifields, as well as in color-fifiltered light fifields. Color-fifiltered light fifields pose particular challenges due to the fact that structures can change signififi- cantly in appearance with wavelength and can completely vanish at some wavelength. We demonstrate solutions to this challenge and obtain a dense sRGB image reconstruction in addition to dense depth maps.
