A comparative study between Elliptic Fourier and B-spline descriptors for object contour representation
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn 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 ... -
Operators to calculate the derivative of digital signals
(2013)
Comunicació de congrés
Accés obertThis paper presents an FIR operator with a very low computational cost for calculating the first derivative of discrete band-limited signals. The basic idea is to use cubic spline polynomials for interpolating among the ...
