Improving Border Localization of Multi-Baseline Stereo Using Border-Cut

Abstract This paper presents a novel algorithm that improves the localization of disparity discontinuities of disparity maps obtained by multi-baseline stereo. Rather than associating a disparity label to every pixel of a disparity map, it associates a position to every … Continue reading

Calibration of Cameras with Radially Symmetric Distortion

calibicon

Abstract We present algorithms for plane-based calibration of general radially distorted cameras. By this we understand cameras that have a distortion center and an optical axis such that the projection rays of pixels lying on a circle centered on the … Continue reading

(English) Fast Lighting/Rendering Solution for Matching a 2D Image to a Database of 3D Models: “Lightsphere”

Abstract We describe a method for object recognition with 2D image queries to be identified from among a set of 3D models. The pose is known from a previous step. The main target application is face recognition. The 3D models … Continue reading

(English) Stereo Without Epipolar Lines : A Maximum-Flow Formulation

Abstract This paper describes a new algorithm for solving the stereo correspondence problem with a global 2-d optimization by transforming it into a maximum-flow problem in a graph. This transformation effectively removes explicit use of epipolar geometry, thus allowing direct … Continue reading
