A micro Lie theory for state estimation in robotics
(2018)
Research report
Open AccessA Lie group is an old mathematical abstract object dating back to the XIX century, when mathematician Sophus Lie laid the foundations of the theory of continuous transformation groups. As it often happens, its usage has ... -
Towards SLAM with an events-based camera
(2016)
Research report
Open AccessEvent-based cameras have an incredible potential in real-time and real-world robotics. They would enable more efficient algorithms in applications where high demanding requirements, such as rapid dynamic motion and high ... -
Comparing error minimized extreme learning machines and support vector sequential feed-forward neural networks
(2010-06)
Research report
Open AccessRecently, error minimized extreme learning machines (EM-ELMs) have been proposed as a simple and efficient approach to build single-hidden-layer feed-forward networks (SLFNs) sequentially. They add random hidden nodes one ... -
Augmented regular expressions: a formalism to describe, recognize, and learn a class of context-sensitive languages
(1995-01-01)
Research report
Open AccessIn order to extend the potential of application of the syntactic approach to pattern recognition, the efficient use of models capable of describing context-sensitive structural relationships is needed. Moreover, the ability ... -
Competitive function approximation for reinforcement learning
(2014)
Research report
Open AccessThe application of reinforcement learning to problems with continuous domains requires representing the value function by means of function approximation. We identify two aspects of reinforcement learning that make the ... -
Modelling of tidal power with EasyJava simulations
(2013-10)
Research report
Open AccessThis report is devoted to the study of a mathematical model to simulte the behaviour of a power generation plant from the ocean tidals. The simulation has been implemented with EasyJava Simulations (EJS) environment. -
Etude d'un canal d'irrigation MIMO
(2011-09-30)
Research report
Restricted access - confidentiality agreementTreball de recerca fet per l'alumne Nicolas Chefdor durant la seva estada al laboratori de recerca VIS-ESAII a la UPC. Dirigit pels Dr. Yolanda Bolea i Dr. Antoni Grau. Estada del 1/06/2011-30/09/2011 -
Stochastic approximations of average values using proportions of samples
(2011)
Research report
Open AccessIn this work we explain how the stochastic approximation of the average of a random variable is carried out when the observations used in the updates consist in proportion of samples rather than complete samples. -
Registration of 3d point clouds for urban robot mapping
(2008)
Research report
Open AccessWe consider the task of mapping pedestrian urban areas for a robotic guidance and surveillance application. This mapping is performed by registering three-dimensional laser range scans acquired with two different robots. To ... -
Path planning with pose SLAM
(2010)
Research report
Open AccessThe probabilistic belief networks that result from standard feature-based simultaneous localization and map building (SLAM) approaches cannot be directly used to plan trajectories. The reason is that they produce a sparse ... -
Estudi de la transformació de l'espai de color RGB a l'espai de color HSV
(2008-09-26)
Research report
Open AccessS’apliquen les tècniques clàssiques de propagació de l’error a la transformació de l’espai de color RGB en l’espai de color HSV a un conjunt de 1098 imatges test. El conjunt d’imatges test són 183 paletes de color i sis ... -
Audio localization for mobile robots
(2009-09-30)
Research report
Open AccessThe department of the University for which I worked is developing a project based on the interaction with robots in the environment. My work was to define an audio system for the robot. This audio system that I have to ...
