A comparative study between Elliptic Fourier and B-spline descriptors for object contour representation
(2014)
Conference report
Restricted access - publisher's policyIn this work, a comparative study between Elliptic Fourier and B-spline descriptors is carried out for comparing their efficiency in characterizing the contour shape of image objects. In both cases, the goal is to obtain ... -

Decimator filter based on B-splines
(2013)
Conference report
Open AccessThe cascaded integrator-comb (CIC) filters are widely used as decimators in many applications, such as in delta sigma AD converters to decimate the sampled signal on its output. One problem with these filters is that by ... -
Divertimento con wavelets
(Universitat Politècnica de Catalunya. Departament d'Enginyeria Electrònica (EEL), 2009)
Conference report
Open AccessEn este trabajo se presenta una pequeña introducción a las wavelets. Estas se interpretan com otra forma de mirar la inormación, formada por diferentes niveles o capas. En concreto se pone el ejemplo de una wavelet basada ... -
Effects of nonidealities in switching frequency modulation techniques:application to Coupled Interleaved Multicellular Parallel converters
(2013)
Conference report
Open AccessThis paper explores the application of the Variable Delay Frequency Modulation (VDFM) to an Interleaved Multicellular Parallel converter. VDFM is a modulation technique specially intended to reduce conducted EMI generated ... -
Efficient cubic spline interpolation implemented with FIR filters
(2012-06-26)
Article
Open AccessClassical Cubic spline interpolation needs to solve a set of equations of high dimension. In this work we show how to compute the interpolant using a FIR digital filter, with a reduced number of operations per interpolated ... -

Efficient representation of contours using splines implemented with FIR filters
(2011)
Conference report
Restricted access - publisher's policyThe interpolation of contour pixels, with splines, of an order greater than or equal to two, usually causes oscillations that do not fit the original shape. To overcome this we propose using a least squares filter before ... -
Feature selection for analyzing and retrieving fish otoliths using elliptic Fourier descriptors of shapes
(2011)
Conference report
Restricted access - publisher's policyThis paper analyzes the characteristics of an experimental otolith retrieval system based on image contours described with Elliptical Fourier Descriptors (EFD). Otoliths are found in the inner ear of fish. Their shape ...
