Second-order motion: Demo

Psychophysical and neurophysiological studies have revealed that the visual system is sensitive to both “first-order” motion, in which moving features are defined by luminance cues, and “second-order” motion, in which motion is defined by nonluminance cues, such as contrast or flicker.

cf.
Lu and Sperling [Vision Res. 35, 2697 (1995)] proposed that human visual motion perception is served by three separate motion systems: a first-order system that responds to moving luminance patterns, a second-order system that responds to moving modulations of feature types―stimuli in which the expected luminance is the same everywhere but an area of higher contrast or of flicker moves, and a third-order system that computes the motion of marked locations in a ‘‘salience map,’’ that is, a neural representation of visual space in which the locations of important visual features (‘‘figure’’) are marked and ‘‘ground’’ is unmarked.
