A satisfiability modulo theories approach to constraint programming
In this thesis we focus on solving CSPs using SMT. Essentially, what we do is reformulating CSPs into SMT. The obtained results allow us to conclude that state-of-the-art SMT solvers are a robust tool to solve CSPs. We ...
Adaptive urban modelling for solar energy simulations
In summary, this thesis proposes to address the problem of simulating physical effects in large urban environments through the use of procedural rules and Level-of-Detail techniques, in order to reduce the computational ...
Advanced techniques in trajectory data analysis for anomaly detection and map construction
With a large amount of trajectory data generated every day, there is a high demand for developing advanced techniques to discover the underlying information instead of dull and heavy manual work. This thesis focuses on the ...
Augmented film narrative by use on non-photorealistic rendering: from 3D cinema to virtual reality
It is stated that non-photorealistic rendering (NPR) triggers specific ocular behaviors that can have a real effect on the way of perceiving a cinematic narrative. The transdisciplinary interest of this thesis lies in ...
Continuity and interpolation techniques for computer graphics
In Computer Graphics applications, it is a common practice to texture 3D models to apply material properties to them. Then, once the models are textured, they are deformed to create new poses that can be more appropriate ...
GPU parallel algorithms for reporting movement behaviour patterns in spatiotemporal databases
In this thesis we treat and solve various problems related to movement pattern detection by designing and implementing parallel algorithms using the GPU. We first propose a GPU pipeline based algorithm to report the ’Popular ...
High dynamic range content acquisition from multiple exposures
The limited dynamic range of digital images can be extended by composing different exposures of the same scene to produce HDR images. This thesis is composed of an overview of the state of the art techniques and three ...
Imaginación visual: nuevo paradigma en interfaces cerebro-máquina
This doctoral thesis focuses on the study of the use of visual imagery for the construction of brain-computer interfaces (BCI) non-invasive. Although the construction of brain-computer interfaces is already is a reality, ...
Medical imaging applied to teaching and meat science
Medical imaging has greatly progressed to become an essential technology in current clinical processes. However, advances in diagnostic imaging have not been applied to the same extent to other fields such as education and ...
Medical imaging techniques for the analysis and measurement of composite materials
The purpose of this thesis is the research and development of methods, algorithms and tools for the analysis of composite materials. In order to improve their properties, one must employ specific techniques in order to ...
Multimodal visualization based on mutual information
Medical imaging and 3D volumetric visualization are a standard routine for patient diagnosis and treatment. Multimodal visualization plays an important role in medical diagnosis and treatment, because it makes findings ...
New solutions to control robotic environments: quality control in food packaging
Machine vision systems and artificial intelligence techniques are two active research areas in the context of Industry 4.0. Their combination allows the reproduction of human procedures while improving the performance ...
Parallel spatial data structures for interactive rendering
The main question explored in this thesis is how to define novel parallel random-access data structures for surface and image spatial data with efficient construction, storage, and query memory access patterns. Our main ...
Perceptual information-theoretic measures for viewpoint selection and object recognition
Viewpoint selection has been an emerging area in computer graphics for some years, and it is now getting maturity with applications in fields such as scene navigation, volume visualization, object recognition, mesh ...
Realistic urban layout modeling from real data
Computer Graphics applications community has big interest on urban modeling and especially on designing complex and realistic cities and buildings. This topic is interesting for film, video game and urbanism industries. ...
Scheduling through logic-based tools
Scheduling problems consist in determining how to execute the activities of a project in order to satisfy some requirements. Such problems are ubiquitous nowadays in industry and services, but finding solutions of scheduling ...
Serious games for visually impaired players and to promote first-aid protocols
Serious games are games designed to entertain and also to teach or transmit some knowledge. They are present in many areas such as military, health, manufacturing, education or medicine, just to name a few. One of their ...
SMT techniques for planning problems
Automated planning is a discipline in the field of Artificial Intelligence that can be described as the process of finding a course of action that achieves a specified task. In other words, it focuses on reasoning about ...
Virtual reality for post-stroke rehabilitation focusing on patients and experts
ENG- Rehabilitation is defined by the World Health Organization as "a set of interventions designed to optimize functioning and reduce disability in individuals with health conditions in interaction with their environment". ...
Voxel-based real-time global illumination
ENG- In this PhD we work in the area of real-time global illumination, proposing three algorithms which contribute to advance in this direction. There are several families of techniques within this area based on research ...
