Charles François (systems scientist) Cybernetics Sciences)Honorary President of the Latin American Association of Systemics (ALAS), Honorary Professor of ITBA, Buenos Aires, and was visiting Professor at various universities and educational institutions in Argentina, Perú and Brasil. He became a member of systemic boards and integrated the editorial boards of various journals on Systems and Cybernetics. In 2007 he received from the American Society for Cybernetics, the Norbert Wiener golden medal as a tribute for his work on cybernetics. In 1952 François came in contact with cybernetics through Norbert Wiener's "Cybernetics". In 1958 he joined the Society for General Systems Research now the International Society
Generalized Wiener filter Generalized Wiener filter The Wiener filter as originally proposed by Norbert Wiener is a signal processing filter which uses knowledge of the statistical properties of both the signal and the noise to reconstruct an optimal estimate of the signal from a noisy one-dimensional time-ordered data stream. The generalized Wiener filter generalizes the same idea beyond the domain of one-dimensional time-ordered signal processing, with two-dimensional image processing being the most common application. Consider a data vector formula_1 which is the sum of independent signal and noise vectors formula_2 with zero mean and covariances formula_3 and formula_4. The generalized Wiener Filter is
