Abstract

The authors report a demonstration in which a motion-defined boundary enhances the effects of a lower region cue in depth perception. Although the lower region cue has been proposed as a potential depth cue, its effect is weak in the static image. Their demonstration reveals that the lower region is almost unambiguously perceived as being in front when defined by horizontal motion mimicking motion parallax. The authors further investigated phenomenological aspects of the lower region cue by combining it with other depth cues.
