Compactly Supported Wavelets Derived From Legendre Polynomials: Spherical Harmonic Wavelets
M. M. S. Lira, H. M. de Oliveira, M. A. Carvalho +1
A new family of wavelets is introduced, which is associated with Legendre polynomials. These wavelets, termed spherical harmonic or Legendre wavelets, possess compact support. The…
A Factorization Scheme for Some Discrete Hartley Transform Matrices
H. M. de Oliveira, R. J. Cintra, R. M. Campello de Souza
Discrete transforms such as the discrete Fourier transform (DFT) and the discrete Hartley transform (DHT) are important tools in numerical analysis. The successful application of t…
Fast Finite Field Hartley Transforms Based on Hadamard Decomposition
H. M. de Oliveira, R. G. F. Távora, R. J. Cintra +1
A new transform over finite fields, the finite field Hartley transform (FFHT), was recently introduced and a number of promising applications on the design of efficient multiple ac…
