Does motion-blur facilitate motion detection ?
Felix A. Wichmann · MPG.PuRe (Max Planck Society) · 1996
Retinal-image motion induces the perceptual loss of high spatial-frequency content - motion blur - that affects broadband stimuli. The relative detectability of motion blur and motion itself, measured in 2-AFC experiments, shows that, although the blur associated with motion can be detected, motion itself is the more effective cue.
