Morphological snakes
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Luis Alvarez, Luis Baumela, Pedro Henriquez, Pablo Marquez-Neila
Issue Date:June 2010
pp. 2197-2202
We introduce a morphological approach to curve evolution. The differential operators used in the standard PDE snake models can be approached using morphological operations on a binary level set. By combining the morphological operators associated to the PD...
A Practical Approach to a Semantic-Based eGovernment Platform. The PLEDGE Project
Found in: Convergence Information Technology, International Conference on
By Luis Álvarez Sabucedo, Luis Anido Rifón, Rubén Míguez Pérez
Issue Date:November 2008
pp. 662-667
In the current state of art for eGovernment solutions, there are several proposals that address the provision of services for citizen. This paper presents a citizen centered approach that takes advantage of current semantic technologies available. This app...
Proposal for a Multiplatform Semantic eGovernment Solution
Found in: Convergence Information Technology, International Conference on
By Luis Álvarez Sabucedo,Luis Anido Rifón
Issue Date:November 2007
pp. 1951-1956
Web platforms are becoming the main support for eGov- ernment solutions. Nevertheless, several drawbacks can be pointed out related to interoperability and accessibility. To overcome this issues and extend the support for a wider range of devices, a new mo...
Life Event Oriented Architecture
Found in: IEEE Services Computing Workshops
By Luis Álvarez Sabucedo, Luis Anido Rifón
Issue Date:September 2006
pp. 86
The huge amount of resources that are being devoted to eGovernmnet projects make it possible the soaring quantity of solutions and projects that are available nowadays. The first consequence is the deficit on interoperability. This paper proposes a approac...
An Ontology Based Architecture for eGovernment Environments
Found in: Enterprise Distributed Object Computing Conference Workshops, IEEE International
By Luis Álvarez Sabucedo, Luis Anido Rifón
Issue Date:October 2007
pp. 165-172
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperab...
A Morphological Approach to Curvature-Based Evolution of Curves and Surfaces
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Pablo Marquez-Neila,Luis Baumela,Luis Alvarez
Issue Date:January 2014
pp. 2-17
We introduce new results connecting differential and morphological operators that provide a formal and theoretically grounded approach for stable and fast contour evolution. Contour evolution algorithms have been extensively used for boundary detection and...
A semantic enrichment experience in the early childhood context
Found in: 2012 IEEE Frontiers in Education Conference (FIE)
By Victor M. Alonso-Roris,Ruben Miguez-Perez,Juan M. Santos-Gago,Luis Alvarez-Sabucedo
Issue Date:October 2012
pp. 1-6
Current society is characterized by an increasing interest in the provision of high-quality Early Childhood Education and Care (ECEC) services. In this area, we developed a platform aimed to create an effortless communication channel among parents and educ...
Segmentation of Computed Tomography 3D Images Using Partial Differential Equations
Found in: Signal-Image Technologies and Internet-Based System, International IEEE Conference on
By Miguel Alem´n-Flores,Luis Alvarez,Patricia Alem´n-Flores,Rafael Fuentes-Pavón
Issue Date:December 2011
pp. 345-349
The analysis of medical images, such as Computed Tomography (CT) Images, increasingly requires an automatic processing for region enhancement, segmentation, 3D reconstruction and many other purposes. This paper presents a framework for performing these tas...
Recursivity and PDE's in Image Processing
Found in: Pattern Recognition, International Conference on
By Luis Alvarez, Francisco Santana, Rachid Deriche
Issue Date:September 2000
pp. 1242
Recursive filtering structures reduce drastically the computational effort required for different tasks in image processing. These operations are done with a fixed number of operations per output point independently of the size of the neighborhood consider...
