Lecture 3: Sampling and Aliasing (8)

Another classic example of the wagon wheel illusion is observing the rotation of car wheels. This is due to the rotation of the wheel being faster than the sampling rate, causing under sampling/aliasing. See this link for a cool example: https://www.youtube.com/watch?v=jHS9JGkEOmA

I think it is interesting that the "wagon wheel" effect might be seen by the naked eye in continuous light in certain situations, such as when the eyes look at a rotating object while physically vibrating. This wikipedia article on the effect cites a paper in which the wagon wheel illusion is observed while humming, causing the eyes to vibrate. https://en.wikipedia.org/wiki/Wagon-wheel_effect#cite_note-6
