Bioinspired parallel 2D or 3D skeletonization
(Universidad de Sevilla, 2013)
Algebraic Topology has been proved to be an useful tool to be used in image processing. In this case we will borrow some elements from Algebraic Topology in order to show a parallel algorithm for thinning a binary 3D image ...

Software tool for contrast enhancement and segmentation of melanoma images based on human perception
(Universidad de Sevilla, 2013)
In this paper we present a software tool for melanoma border detection (MBD). It has been designed to be incorporated in any Computer Aided Diagnosis Tool (CAD) for early detection of melanoma in mass screening programs. ...

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 ...

An application for gait recognition using persistent homology
(Universidad de Sevilla, 2013)
This Demo presents an application for gait recognition using persistent homology. Using a background subtraction approach, a silhouette sequence is obtained from a camera in a controlled environment. A border simplicial ...

Distributed boundary tracking using alpha and Delaunay-Cech shapes
(Universidad de Sevilla, 2013)
We demonstrate real time tracking of systematic failures in sensor networks, using distributed computation of the α−shape derived from the network. More generally, our work may be applied to tracking the boundary of any ...

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 ...

Interactive display of 2D and 3D discrete quadrics with controlled topology
(Universidad de Sevilla, 2013)
In this demonstration, we are going to propose an interactive animation of analytically defined discrete conics (quadrics in 2D) and discrete quadrics in 3D. The digitization is performed on the 2D quadratic equation: Ax2 ...

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 ...
