Regular map smoothing
(Universidad de Sevilla, 2013)
A regular map is a family of equivalent polygons, glued together to form a closed surface without boundaries which is vertex, edge and face transitive. The commonly known regular maps are derived from the Platonic solids ...

TKDetection: a software to detect and segment wood knots
(Universidad de Sevilla, 2013)
TKDetection is a software proposing to segment the wood knots obtained from X-Ray Computed Tomography (CT) scanners. It implements algorithms combining tools of image analysis and discrete geometry, like connected component ...

Calibration in optical graph recognition
(Universidad de Sevilla, 2013)
Graph drawing is the process of transforming the topological structure of a graph into a graphical representation. Primarily, it maps vertices to points and displays them by icons, and it maps edges to Jordan curves ...

Reconstructing persistent graph structures from noisy images
(Universidad de Sevilla, 2013)
Let a point cloud be a noisy dotted image of a graph on the plane. We present a new fast algorithm for reconstructing the original graph from the given point cloud. Degrees of vertices in the graph are found by methods of ...

Implementation of Integral based Digital Curvature Estimators in DGtal
(Universidad de Sevilla, 2013)
In many geometry processing applications, differential geometric quantities estimation such as curvature or normal vector field is an essential step. In [1], we have defined curvature estimators on digital shape boundaries ...
