Quality Measurement Model for Analysis and Design Tools Based on FLOSS
Software Engineering Conference, Australian
By O. Alfonzo, K. Domínguez, L. Rivas, M. Pérez, L. Mendoza, M. Ortega
Issue Date:March 2008
The selection of Free/Libre Open Source Software (FLOSS) tools for Analysis and Design (A&D) is a hard task due to their complexity, their wide variety within the market, and their functionality level. This article aims at introducing a group of qualit...
Measuring changes in face appearance through aging
Computer Vision and Pattern Recognition Workshop
By M. Ortega, L. Brodo, M. Bicego, M. Tistarelli
Issue Date:June 2009
Facial aging has been only partially studied in the past and mostly in a qualitative way. This paper presents a novel approach to the estimation of facial aging aimed to the quantitative evaluation of the changes in facial appearance over time. In particul...

The Therapeutic Lamp: Treating Small-Animal Phobias
IEEE Computer Graphics and Applications
By M. Wrzesien,M. Alcañiz,C. Botella,J-M Burkhardt,J. Bretón-López,M. Ortega,D. B. Brotons
Issue Date:January 2013
We all have an irrational fear or two. Some of us get scared by an unexpected visit from a spider in our house; others get nervous when they look down from a high building. Fear is an evolutionary and adaptive function that can promote self-preservation an...
Automatic Analysis of the Patient's Conscious Responses to the Emission of Auditory Stimuli during the Performance of an Audiometry
Digital Image Computing: Techniques and Applications
By A. Fernandez,M.G. Penedo,M. Ortega,B. Cancela,C. Vazquez,L.M. Gigirey
Issue Date:December 2011
This paper presents a methodology for the automatic detection of human conscious responses to different auditory stimuli during the performance of an audiogram. An audiogram is the standard way of analyze the hearing of a patient in order to diagnose heari...
Automatic cyst detection in OCT retinal images combining region flooding and texture analysis
2013 IEEE 26th International Symposium on Computer-Based Medical Systems (CBMS)
By A. Gonzalez,B. Remeseiro,M. Ortega,M. G. Penedo,P. Charlon
Issue Date:June 2013
In this work Optical Coherence Tomography (OCT) retinal images are automatically processed to detect the presence of cysts. The methodology is composed by three phases: region of interest where cysts will be searched is delimited; a watershed algorithm is ...
Measuring response times to auditory stimuli during an audiometry
Found in: Proceedings of the 4th International Symposium on Applied Sciences in Biomedical and Communication Technologies (ISABEL '11)
By A. Fernandez, B. Cancela, C. Vazquez, L. M. Gigirey, M. G. Penedo, M. Ortega
Issue Date:October 2011
This paper provides a methodology for the measure of the patient's reaction times to auditory stimuli during the performance of an audiometry. An audiometry is the standard way of analyzing the hearing of a patient in order to diagnose hearing loss. From a...
A Six Degree-of-Freedom God-Object Method for Haptic Display of Rigid Bodies with Surface Properties
IEEE Transactions on Visualization and Computer Graphics
By M. Ortega,S. Redon,S. Coquillart
Issue Date:May 2007
This paper describes a generalization of the god-object method for haptic interaction between rigid bodies. Our approach separates the computation of the motion of the six degree-of-freedom god-object from the computation of the force applied to the user. ...
Planning in problem solving: a case study in domotics
Frontiers in Education, Annual
By J. Bravo, M. Ortega, F. Verdejo
Issue Date:October 2000
Simulation environments requiring the creation of a model previous to the simulation stage raise a challenge for the student. In these environments, the realization of the model itself, which is the basis for most of the richness of the acquired knowledge,...
Multicoloring with lots of colors
Proceedings of the 3rd international conference on Supercomputing (ICS '89)
By D. L. Harrar, J. M. Ortega
Issue Date:June 1989
The initial results of the iterative Arnoldi-Tchebychev procedure for the eigensolutions of large scale nonsymmetric matrices are discussed. The procedure uses an accurate algorithm for the identification of the optimal Tchebychev ellipse relative to a com...
On Sturm Sequences for Tridiagonal Matrices
Journal of the ACM (JACM)
By J. M. Ortega
Issue Date:July 1960
The consistency of precedence matrices is studied in the very natural geometric setting of the theory of directed graphs. An elegant recent procedure (Marimont ) for checking consistency is further justified by means of a graphical lemma. In addition, t...
