2D Euclidean distance transform algorithms: A comparative survey

R Fabbri, LDF Costa, JC Torelli, OM Bruno - ACM Computing Surveys …, 2008 - dl.acm.org
The distance transform (DT) is a general operator forming the basis of many methods in
computer vision and geometry, with great potential for practical applications. However, all the …

3D curve sketch: Flexible curve-based stereo reconstruction and calibration

R Fabbri, B Kimia - 2010 IEEE Computer Society Conference …, 2010 - ieeexplore.ieee.org
Interest point-based multiview 3D reconstruction and calibration methods have been very
successful in select applications but are not applicable when an abundance of feature points …

On Voronoi diagrams and medial axes

R Fabbri, LF Estrozi, LDF Costa - Journal of Mathematical Imaging and …, 2002 - Springer
Medial axes and Voronoi diagrams stand among the most influencing ideas in computer
vision and image analysis. Relationships between them, with respect to polygons, had been …

Trplp-trifocal relative pose from lines at points

R Fabbri, T Duff, H Fan, MH Regan… - Proceedings of the …, 2020 - openaccess.thecvf.com
We present a method for solving two minimal problems for relative camera pose estimation
from three views, which are based on three view correspondences of (i) three points and one …

From multiview image curves to 3D drawings

A Usumezbas, R Fabbri, BB Kimia - … 11–14, 2016, Proceedings, Part IV 14, 2016 - Springer
Reconstructing 3D scenes from multiple views has made impressive strides in recent years,
chiefly by correlating isolated feature points, intensity patterns, or curvilinear structures. In …

Multiview differential geometry of curves

R Fabbri, BB Kimia - International Journal of Computer Vision, 2016 - Springer
The field of multiple view geometry has seen tremendous progress in reconstruction and
calibration due to methods for extracting reliable point features and key developments in …

Camera pose estimation using first-order curve differential geometry

R Fabbri, BB Kimia, PJ Giblin - … Computer Vision, Florence, Italy, October 7 …, 2012 - Springer
This paper considers and solves the problem of estimating camera pose given a pair of point-tangent
correspondences between the 3D scene and the projected image. The problem …
