Classical models for information transmission such as Shannon and Weaver's still tend to be looked at as the only possible scenarios where signal processing applications can be formally modeled. Meanwhile, other disciplines ...
Restoration of a high-quality image from a degraded recording is an important problem in early vision processing. In this thesis, we tackle three image restoration problems: image inpainting, colorization, and motion ...
Portable and interactive technologies are changing the nature of collaborative learning practices. Learning can now occur both in and beyond the classroom and furthermore combine formal and informal activities monitored ...
Motion estimation plays a key role in many of the image processing and computer vision problems. This thesis addresses the problem of recovering a dense motion field from a scene through the Calculus of Variations. In ...
Computer-supported collaborative learning (CSCL) creates avenues for productive collaboration between students. In CSCL, collaborative learning flow patterns (CLFPs) provide pedagogical rationale and constraints for ...
Elliptic curves with a bilinear map, or pairing, have a rich algebraic structure that has been fundamental to develop practical Non-Interactive Zero-Knowledge (NIZK) proofs. On the theoretical side, we explore how efficient ...
Due to the recent advances in virtual and augmented reality, ambisonics has emerged as the de facto standard for immersive audio. Ambisonic audio can be captured using spherical microphone arrays, which are becoming ...
Els models neuronals de camp mig són descripcions fenomenològiques de l'activitat de xarxes de neurones espacialment organitzades. Gràcies a la seva simplicitat, aquests models són unes eines extremadament útils per a ...
Current information technologies allow users to interact and collaborate to create fictional realities. In this thesis, we explore the role of perceived consistency and coherence in the collaborative creation of fictional ...
The cinema and television industries are continuously working in the development of image features that can provide a better visual experience to viewers; these image attributes include large spatial resolution, high ...
Intelligent Transport Systems (ITS) are aiming to provide innovative services related to different modes of transport and traffic management, and enable various users to be better informed and make safer, more coordinated ...
This thesis presents new phase-based signal analysis techniques to study brain dynamics from patients with pharmacoresistant focalonset epilepsy. We analyze electroencephalographic (EEG) recordings from seizure and ...
Plan recognition is the problem of inferring the goals and plans of an agent after partially observing its behavior. This is the inverse of planning, the problem of finding the actions that need to be done in order to ...
Predictions about the evolution of the Internet of Things (IoT) in the next years are optimistic. The number of interconnected devices will continue to grow exponentially, as well as the amount of data that they report. Part ...
The increase in stroke survivors poses a global challenge for the current health care system. The way that standard therapy is provided today impacts long-term disability and dependency in ADL insufficiently. The associated ...
Updating beliefs to maintain coherence with observational evidence is a cornerstone of rationality. This entails the compliance with probabilistic principles which acknowledge that real-world observations are consistent ...
Generalized planning is the problem of finding an algorithm-like solution called generalized plan to multiple planning instances. The two main tasks to perform in generalized planning are synthesizing and validating ...
Adult Spine Deformity (ASD) leads to abnormal spine curvature causing imbalance, pain, and fall risk. Spinal surgery is common but carries the risk of Mechanical Complications (MC), notably Proximal Junctional Failure ...
The constant development of ubiquitous computing has enabled the pervasive integration of sensing and display technologies in everyday public settings. Urban digital screens are increasingly dominating the visual cityscape, ...
Nowadays, the amount of available digital documents is rapidly growing, expanding at a considerable rate and coming from a variety of sources. Sources of unstructured and semi-structured information include the World ...
