In 1990, he showed that the
binomial quadrature mirror filter bank (binomial QMF) is identical to the
Daubechies wavelet filter, and interpreted and evaluated its performance from a discrete-time signal processing perspective. [5] It was an extension of his prior work on
Binomial coefficient and
Hermite polynomials that he developed the Modified Hermite Transformation (MHT) in 1987.[6][7] The magnitude square functions of
Binomial-QMF filters were shown to be the unique maximally flat functions in a two-band PR-QMF design formulation.[8][9] He organized the first
wavelet conference in the United States at NJIT in April 1990,[10] and, then in 1992[11] and 1994.[12] He published the first
wavelet-related engineering book in the literature entitled Multiresolution Signal Decomposition: Transforms, Subbands and Wavelets in 1992.[13]
Akansu was a founding director of the New Jersey Center for Multimedia Research (NJCMR), 1996–2000, and NSF Industry-University Cooperative Research Center (IUCRC) for Digital Video, 1998–2000. He was the vice president for research and development of the
IDT Corporation, 2000–2001, the founding president and CEO of PixWave, Inc. (an
IDT Entertainment subsidiary) that has built the technology for secure
peer-to-peer video distribution over the Internet. He was an academic visitor at David Sarnoff Research Center (
Sarnoff Corporation), at IBM's
Thomas J. Watson Research Center, and at
Marconi Electronic Systems.
He is an
IEEE Fellow (since 2008) with the citation for contributions to optimal design of transforms and filter banks for communications and multimedia security.[36]
