Real-time visibility-based fusion of depth maps
(2007)2007 IEEE 11th International Conference on Computer VisionWe present a viewpoint-based approach for the quick fusion of multiple stereo depth maps. Our method selects depth estimates for each pixel that minimize violations of visibility constraints and thus remove errors and inconsistencies from the depth maps to produce a consistent surface. We advocate a two-stage process in which the first stage generates potentially noisy, overlapping depth maps from a set of calibrated images and the second ...Conference Paper -

Evaluation of Large Scale Scene Reconstruction
(2007)2007 IEEE 11th International Conference on Computer VisionWe present an evaluation methodology and data for large scale video-based 3D reconstruction. We evaluate the effects of several parameters and draw conclusions that can be useful for practical systems operating in uncontrolled environments Unlike the benchmark datasets used for the binocular stereo and multi-view reconstruction evaluations, which were collected under well-controlled conditions, our datasets are captured outdoors using ...Conference Paper -

Joint Feature Tracking and Radiometric Calibration from Auto-Exposure Video
(2007)2007 IEEE 11th International Conference on Computer VisionTo capture the full brightness range of natural scenes, cameras automatically adjust the exposure value which causes the brightness of scene points to change from frame to frame. Given such a video sequence, we introduce a new method for tracking features and estimating the radiometric response function of the camera and the exposure difference between frames simultaneously. We model the global and nonlinear process that is responsible ...Conference Paper -
