Fuchs et al. [2010] use per-pixel temporal filters to dampen temporal
aliasing of motion in videos. They also discuss the high-pass
filtering of motion, but mostly for non-photorealistic effects and for
large motions (Figure 11 in their paper). In contrast, our method
strives to make imperceptible motions visible using a multiscale
approach. We analyze our method theoretically and show that it
applies only for small motions.
