Two-dimensional nonseparable discrete linear canonical transform based on CM-CC-CM-CC decomposition
Soo-Chang Pei, Shih-Gu Huang
As a generalization of the two-dimensional Fourier transform (2D FT) and 2D fractional Fourier transform, the 2D nonseparable linear canonical transform (2D NsLCT) is useful in opt…

Discrete Gyrator Transforms: Computational Algorithms and Applications
Soo-Chang Pei, Shih-Gu Huang, Jian-Jiun Ding
As an extension of the 2D fractional Fourier transform (FRFT) and a special case of the 2D linear canonical transform (LCT), the gyrator transform was introduced to produce rotatio…
