Morphological operators for image and video compression
(1996-06)
Article
Accés obertThis paper deals with the use of some morphological tools for image and video coding. Mathematical morphology can be considered as a shape-oriented approach to signal processing, and some of its features make it very useful ... -
On the zero- and first-order interpolation in synthesized wave for testing purposes
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1992-12-02)
Article
Accés obertThis paper deals with the quality requirements of synthesized sine waves reconstructed through a zero- or first- order hold for testing purposes, in particular when a switching demodulator is used. In this case, the ... -
Optimization of a procedure for model calibration using a method based on scattered data interpolation
(International Institute of Refrigeration, 2019)
Text en actes de congrés
Accés restringit per política de l'editorialIn order to develop advanced control strategies for complex thermal systems such as in the case of refrigeration and air-conditioning systems, calibrated models against experimental measurements are necessary to reproduce ... -
Order regularity for Birkhoff interpolation with lacunary polynomials
(2011-06-01)
Article
Accés obertIn this short paper we present sufficient conditions for the order regularity problem in Birkhoff interpolation with lacunary polynomials. These conditions are a generalization of the Atkinson-Sharma theorem. -
Prediction of image partitions using Fourier descriptors: application to segmentation-based coding schemes
(1998-04)
Article
Accés obertThis paper presents a prediction technique for partition sequences. It uses a region-by-region approach that consists of four steps: region parameterization, region prediction, region ordering, and partition creation. The ... -
Reduction of individual sampling rates by generalizing quadrature methods of separate interpolation
(Acoustical Society of America, 1981-11)
Article
Accés obert -
Robust eye tracking based on multiple corneal reflections for clinical applications

Robust TDOA Estimation in a Continuous Stereo Audio Track
(Universitat Politècnica de Catalunya / Universität Freiburg im Breisgau, 2013-12-16)
Projecte/Treball Final de Carrera
Accés obert
Realitzat a/amb: Universität Freiburg im Breisgau[ANGLÈS] Algorithm realization based on the time difference of arrivals (TDOA) of two signals caught by two microphones coming from the voice of a speaker in order to define their position by using the phase correlation ... -
Some non-standard sobolev spaces, interpolation and its application to PDE
(2012-10)
Article
Accés restringit per política de l'editorialWe consider some nonstandard Sobolev spaces in one dimension, in which functions have different regularity in different subsets. These spaces are useful in the study of some nonlinear parabolic equations where the ... -
Specific 2-D spectral estimation for wideband beamforming
(Institute of Electrical and Electronics Engineers (IEEE), 1990)
Text en actes de congrés
Accés obert -
Spectral iterative algorithm for RCS computation in electrically large or intermediate perfectly conducting cavities
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1994-06-01)
Article
Accés obertA novel algorithm designed to compute efficiently and accurately the high-frequency electromagnetic scattering from open-ended waveguide cavities is presented. The cavity is converted into a stepped-waveguide model so that ... -
Study of manifold interpolation techniques for acceleration of Stokes flow simulation
(Universitat Politècnica de Catalunya, 2023-07-14)
Treball Final de Grau
Accés obertThis thesis investigates interpolation techniques for modeling the velocity field in the Lid-Driven Cavity with Stokes flow, inspired by the potential utility of these techniques in the aeronautical field to reduce ... -
