Hyperspectral Light Field Stereo Matching
In this paper, we describe how scene depth can be extracted using a hyperspectral light field capture (H-LF) system. Our H-LF system consists of a 5× 6 array of cameras, with each camera sampling a different narrow band in the visible spectrum. There are two parts to extracting scene depth. The first part is our novel cross-spectral pairwise matching technique, which involves a new spectral-inv...
متن کاملOptimizing Disparity Candidates Space in Dense Stereo Matching
In this paper, a new approach for optimizing disparity candidates space is proposed for the solution of dense stereo matching problem. The main objectives of this approachare the reduction of average number of disparity candidates per pixel with low computational cost and high assurance of retaining the correct answer. These can be realized due to the effective use of multiple radial windows, i...
متن کاملNear-Field Photometric Stereo in Ambient Light
Shape recovery from shading information has recently regained importance due to the improvement towards making the Photometric Stereo technique more reliable in terms of appearance of reflective objects. However, although more advanced models have been lately proposed, 3D scanners based on this technology do not provide reliable reconstructions as long as the considered irradiance equation negl...
متن کاملLight Field Assisted Stereo Matching using Depth from Focus and Image-Guided Cost-Volume Filtering
Light field photography advances upon current digital imaging technology by making it possible to adjust focus after capturing a photograph. This capability is enabled by an array of microlenses mounted above the image sensor, allowing the camera to simultaneously capture both light intensity and approximate angle of incidence. The ability to adjust focus after capture makes light field photogr...
متن کاملNear Field Photometric Stereo with Point Light Sources
Shape recovery of an object based on shading variations resulting from different light sources has recently been reconsidered. Improvements have been made that allow for the photometric stereo approach to serve as a competitive alternative to other shape reconstruction methods. However, most photometric stereo methods tend to ignore factors that are relevant in practical applications. The setup...
