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 ...
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 ...
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 ...
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 ...
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 ...
Serious games are video games designed to provide specific expertise, knowledge and skills to the player, going beyond pure entertainment. In this thesis we present a classification of serious games for health and medicine ...
Compositional data are defined as vectors of components that represent parts of a whole and contain relative information (e.g. %, ppm, mg/l...). CoDa are widely found in chemical, pharmaceutical and food industries among ...
We are in the information age where most data is stored in digital format. Thus, the management of digital documents and videos requires the development of efficient techniques for automatic analysis. Among them, capturing ...
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 ...
In this thesis we focus on reformulate constraint satisfaction problems (CSP) into SAT Modulo Theories (SMT). SMT is an extension of SAT where the literals appearing in the formulas are not restricted to contain only ...
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. ...
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 ...
The human brain is a complex network that shares and processes information by using the structural paths between areas in order to perform a function. The connectome models the brain as a graph where nodes correspond to ...
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 ...
The present thesis is a compendium of three original works produced between 2014 and 2018. The papers have a common link: they are different contributions made by compositional data analysis to the study of the models based ...
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 ...
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 ...
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 ...
Nowadays, the improvement in Computer Graphics has benefited fields such as Cultural Heritage, where the main efforts have focused on the digital preservation of historic buildings or urban structures. In this thesis, ...
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 ...
