If you're thinking of taking a look, I particularly enjoyed Lecture 7 of this series. The practical applications of Fourier analysis in image recognition/filtering/processing are really quite amazing. Plus, if you're at all curious about the technical details for how exactly something like Night Sight is implemented on the Pixel, understanding what Fourier transformations are and how they are utilized is vital.
