Uncertainty principle for 2D discrete signals

Abstract

In this talk, the uncertainty principle for 2D discrete signals associated with quaternion Fourier transform is obtained. As an application, it explains an interesting phenomena in signal recovery problems where there is an interplay of missing data and time-limiting.
