Spectral graph fractional Fourier transform for directed graphs and its application
Fang-Jia Yan, Bing-Zhao Li
In graph signal processing, many studies assume that the underlying network is undirected. Although the digraph model is rarely adopted, it is more appropriate for many application…

Uncertainty principle for the two-sided quaternion windowed linear canonical transform
Wen-Biao Gao, Bing-Zhao Li
In this paper, we investigate the (two-sided) quaternion windowed linear canonical transform (QWLCT) and study the uncertainty principles associated with the QWLCT. Firstly, severa…

Quaternion Windowed Linear Canonical Transform of Two-Dimensional Quaternionic Signals
Wen-Biao Gao, Bing-Zhao Li
We investigate the 2D quaternion windowed linear canonical transform(QWLCT) in this paper. Firstly, we propose the new definition of the QWLCT, and then several important propertie…
