It is well known that time-frequency analysis (TFA) characterises signals in time-frequency
plane. Theoretically, traditional non-parameterised TFA can analyze any signal, but it is …

Hyperspectral videos (HSVs) play an important role in the monitoring domain, as they can
provide more information than red–green–blue (RGB) videos about the movement of …

The Fractional Fourier transform (FRFT) is a relatively novel linear transforms that is a
generalization of conventional Fourier transform (FT). FRFT can transform a particular signal …

The intricate vibration of a working vehicle provides an important signature to the vehicle
