Perceiving three-dimensional objects during egomotion

Classes of powerful stimuli that reliably elicit wrong depth percepts are examined. The depth percepts in turn cause the stimuli to appear to move vividly as observers move in front of them. These illusory percepts highlight the issue of how we obtain a stable percept of the environment as we move about, despite considerable changes in the retinal images. Experimental results on the role of pictorial cues, and possible explanations for the illusory motion are presented. The interaction of data-driven mechanisms and schema-driven cognitive processes is examined
