The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

A Frequency Domain Approach to Registration of Aliased Images with Application to Super-resolution (2006, methodology): “Kim and Su [19], Stone et al. [20], and Vandewalle et al. [2] also apply a phase correlation technique to estimate planar shifts.”
Automatic and Precise Orthorectification, Coregistration, and Subpixel Correlation of Satellite Images, Application to Ground Deformation Measurements (2007, background): “The phase slope might be estimated by least square adjustment with possibly some weighting to filter out the effect of noise and aliasing at high frequencies [28].”
Burst photography for high dynamic range and low-light imaging on mobile cameras (2016, methodology): “This improves on the standard approach of fitting two separable functions [Stone et al. 2001] by avoiding the assumption that motion is independently constrained to the respective axes.”
