Perception of motion direction in luminance-and contrast-defined reversed-phi motion sequences
Perception of motion direction in luminance-and contrast-defined reversed-phi motion sequences is a scholarly work by Alan Johnston, published in 1997 in ''Vision Research''. The main subjects of the publication include modulation, optics, contrast, physics, artificial intelligence, psychology, stimulus, spatial frequency, computer vision, perception, motion perception, luminance, communication, psychophysics, motion, Percept, and visual perception. The authors examined perceived direction of motion for stimuli in which these reversed motion sequences were used to modulate the contrast of binary noise patterns.
