Privatization of Probability Distributions by the Wavelet Integral approach
Helio M. de Oliveira, Raydonal Ospina, Victor Leiva +2
A naive theory of additive perturbations on a continuous probability distribution is presented. We propose a new privatization mechanism based on a naive theory of a perturbation o…
Rounded Hartley Transform: A Quasi-involution
R. J. Cintra, H. M. de Oliveira, C. O. Cintra
A new multiplication-free transform derived from DHT is introduced: the RHT. Investigations on the properties of the RHT led us to the concept of weak-inversion. Using new construc…
Multidimensional Wavelets for Scalable Image Decomposition: Orbital Wavelets
H. M. de Oliveira, V. V. Vermehren, R. J. Cintra
Wavelets are closely related to the Schrödinger's wave functions and the interpretation of Born. Similarly to the appearance of atomic orbital, it is proposed to combine anti-symme…
von Mises Tapering: A Circular Data Windowing
H. M. de Oliveira, F. Chaves
Continuous standard windowing is revisited and a new taper shape is introduced, which is based on the normal circular distribution by von Mises. Continuous-time windows are conside…
