Depth Estimation for Glossy Surfaces with Light-Field Cameras
Light-field cameras have now become available in both consumer and industrial applications, and recent papers have demonstrated practical algorithms for depth recovery from a passive single-shot capture. However, current lightfield depth estimation methods are designed for Lambertian objects and fail or degrade for glossy or specular surfaces. Because light-field cameras have an array of micro-...
متن کاملDepth Estimation Through a Generative Model of Light Field Synthesis
Outline. We show our results on various datasets, including images taken with the Lytro by Tao et al. [2013] and our own dataset, images from the Stanford light field dataset [sta, 2008] and results on an artificial dataset [Wanner et al., 2013]. Furthermore, we expand on details such as the triangular function and the selection of the parameters. Finally, we discuss implications of our no-occl...
متن کاملDepth Estimation of Light Field Images by Optical Flow
Light field images present a rich, compact, dataset of multiple images of a scene from slightly shifted viewpoints. I explore the use of an optical flow algorithm on light field images to estimate depth. The optical flow algorithm is simple to implement as does not require finding correspondences between images. Further, I explore the use of image priors and modern optimization techniques to fo...
متن کاملJoint Blind Motion Deblurring and Depth Estimation of Light Field
Removing camera motion blur from a single light field is a challenging task since it is highly ill-posed inverse problem. The problem becomes even worse when blur kernel varies spatially due to scene depth variation and high-order camera motion. In this paper, we propose a novel algorithm to estimate all blur model variables jointly, including latent sub-aperture image, camera motion, and scene...
متن کاملExtended Depth of Field for Fluorescence Microscopy
High numerical aperture objectives result in extremely shallow depths of field, which may or may not be desired by the user of the microscope. When looking at extended objects, planes that arent necessarily perpendicular to the light path, or fluorophores that move in and out of focus, an extended depth of field (EDOF) would be useful to fully visualize the sample. PSF engineering can be applie...
