[ES]: La economía tradicional explica la evolución de los individuos y del conocimiento de forma muy parcial. Los nuevos medios exigen una reconsideración del papel del individuo y del valor comunal del conocimiento que permita una reorientación del sentido económico y las acciones individuales. Frente a la teoría de juegos tradicional de suma 0, e...

This paper presents a variation of the classic algorithm of active contours in order to improve the visualization of D reconstruction of anatomical structures in medicine. This 3D reconstructions are made from the obtained contours. This variation of active contour enables a better behavior of them.Other authors have already used snakes (active con...

This paper present a method for image segmentation, which is an adaptation of the classical active contours algorithm, also called "snakes", using a new internal energy approach. The classical model computes the energy function based on changes in gradient values, thus determining the detection of the object's edges. In the proposed model, the acti...

The aim of this paper is to show a way of applying Bayesian inference on interval fuzzy data assuming that all the time we work with interval probabilities. The proposal is illustrated with an example in Health Care, specifically on inferring population annoyance level caused by noise exposure.
Conference Paper
Too many people suffer from noise levels that scientists and health experts consider to be unacceptable, where most people become annoyed, where sleep is disturbed and where adverse health effects are to be feared. The present paper centers on inferring individuals annoyance level caused by noise exposure. The starting point of our thoughts is the...

Article
In many scientific and technical applications, a three-dimensional (3D) object must be reconstructed, either to assist in understanding the object's structure or to ease its automatic handling and analysis. Volume reconstruction has been used in health care to diagnose, simulate, facilitate surgical planning, develop image-guided surgery, facilitat...

Conference Paper
Full-text available
We introduce a family of divergences between φ-probabilistic sets, with real supports. The supports are never unbounded to opposite sides. We start from weighted and percentiled dissimilarities between arbitrary unions of compact intervals of real numbers. As an application we model the problem of the recognition of a handshape as a metric problem...
