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. ...

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 ...

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 ...
