Generalization of time-frequency signal representations to joint fractional Fourier domains
(IEEE, 2005-09)The 2-D signal representations of variables rather than time and frequency have been proposed based on either Hermitian or unitary operators. As an alternative to the theoretical derivations based on operators, we propose ... -
A signal representation approach for discrimination between full and empty hazelnuts
(IEEE, 2007)We apply a sparse signal representation approach to impact acoustic signals to discriminate between empty and full hazelnuts. The impact acoustic signals are recorded by dropping the hazelnut shells on a metal plate. The ...
