Multiview Photometric Stereo [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2008
This paper addresses the problem of obtaining complete, detailed reconstructions of textureless shiny objects. We present an algorithm which uses silhouettes of the object, as well as images obtained under changing illumination conditions. In contrast with previous photometric stereo techniques, ours is not limited to a single viewpoint but produces ...

Photometric stereo endoscopy [PDF]

Journal of Biomedical Optics, 2013
While color video endoscopy has enabled wide-field examination of the gastrointestinal tract, it often misses or incorrectly classifies lesions. Many of these missed lesions exhibit characteristic three-dimensional surface topographies. An endoscopic system that adds topographical measurements to conventional color imagery could therefore increase ...

Photometric redshifts from reconstructed QSO templates [PDF]

, 2001
From SDSS commissioning photometric and spectroscopic data, we investigate the utility of photometric redshift techniques to the task of estimating QSO redshifts. We consider empirical methods (e.g.

Photometric Visual Servoing [PDF]

IEEE Transactions on Robotics, 2011
This paper proposes a new way to achieve robotic tasks by 2D visual servoing. Indeed, instead of using classical geometric features such as points, straight lines, pose or a homography, as is usually done, the luminance of all pixels in the image is here considered.

Photometric Segmentation: Simultaneous Photometric Stereo and Masking [PDF]

2019 International Conference on 3D Vision (3DV), 2019
This work is concerned with both the 3D-reconstruction of an object using photometric stereo, and its 2D-segmentation from the background. In contrast with previous works on photometric stereo which assume that a mask of the area of interest has been computed beforehand, we formulate 3D-reconstruction and 2D-segmentation as a joint problem.

SDSS Standard Star Catalog for Stripe 82: the Dawn of Industrial 1% Optical Photometry [PDF]

, 2007
We describe a standard star catalog constructed using multiple SDSS photometric observations (at least four per band, with a median of ten) in the $ugriz$ system.
