It has been shown that the fractional Fourier transform, recently very intensively investigated in mathematics, quantum mechanics, optics and signal processing, can be obtained as a special case of the earlier introduced linear coordinate transformations of the ambiguity function or Wigner distribution. Some applications of the generalized fractional transform on the time-frequency analysis are...

This paper studies a suitably normalized set of generalized Hermite polynomials and sets down a relevant Mehler formula, Rodrigues formula, and generalized translation operator. Weighted generalized Hermite polynomials are the eigenfunctions of a generalized Fourier transform which satisfies an F. and M. Riesz theorem on the absolute continuity of analytic measures. The Bose-like oscillator cal...

As 3D scanning devices and depth sensors advance, dynamic point clouds have attracted increasing attention as a format for objects in motion, with applications various fields such immersive telepresence, navigation autonomous driving gaming. Nevertheless, the tremendous amount of data significantly burden transmission storage. To this end, we propose complete compression framework attributes cl...
