| contents | This comprehensive review paper delves into the intricacies of advanced Fourier type integral transforms and their mathematical properties, with a particular focus on fractional Fourier transform (FrFT), linear canonical transform (LCT), quadratic phase Fourier transform (QPFT), and their associated offshoots: windowed Fourier transform, wavelet transform, and Stockwell transform. In the pursuit of a deeper understanding of these transformations, we explore their convolution properties, shedding light on their capacity to define windowed, wavelet and Stockwell transforms in the realm of Fourier, fractional Fourier and quadratic phase Fourier transforms. This review also expands its purview to the realm of uncertainty principles. Several uncertainty principles, like Heisenberg, logarithmic, local, Rényi uncertainty principles, etc., within the context of fractional Fourier, linear canonical, and quadratic phase Fourier transforms, as well as their derivative offshoots are presented in the paper both for the functions of complex as well as quatenrion valued. In particular, the counterpart of several important inequalities of classical Fourier transform are also presented in details for the quaternion case. This article also reviews that multiresolution analysis that has been developed in the literature so far. |
