Wu-Sheng Lu1983Your 1981-84 student, who has been with Univ. ofVictoria, Canada, since 1987. Some of the things that were started, in one way oranother, at U of M under your guidance Wrote a book (with my Victoria colleagueAndreas Antoniou) on “Two-DimensionalDigital Filters”, Marcel Dekker, 1991. Elevated to the Fellow grade in IEEE(1999) for the work on multidimensionalsystems and digital filters. In a finishing stage of second book (withAndreas Antoniou) on “Optimization:Methods, Algorithms, and Applications”,Kluwer Academic, 2002.
