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 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 ...
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 ...
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 ...
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 ...
ENG- Compositional data are a special type of multivariate data where the variables represent parts of a whole. These data are commonly encountered in fields such as geology, biology, economics, and chemistry, where the ...
The present thesis is a compendium of three research articles produced between 2015 and 2019. The three articles are different contributions based on compositional statistical methodology and statistical inference of ...
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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
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 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 ...
RGB-D cameras return images like an ordinary camera but in addition to color, depthmaps where each pixel value represents the distance to a point of the scene are also obtained. Although originally conceived for gaming and ...
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 ...
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 ...
The present doctoral thesis explores an e-learning proposal fruit of using Information and Communication Technologies (ICT) with the objective of improving students’ learning experience. The proposal aims to facilitate the ...
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 ...
