Depth Estimation during Fixational Head Movements in a Humanoid Robot
Under natural viewing conditions, humans are not aware of continually performing small head and eye movements in the periods in between voluntary relocations of gaze. It has been recently shown that these fixational head movements provide useful depth information in the form of parallax. Here, we replicate this coordinated head and eye movements in a humanoid robot and describe a method for ext...
متن کاملFixational eye movements and perception
http://dx.doi.org/10.1016/j.visres.2015.12.001 0042-6989/Published by Elsevier Ltd. Visual perception is a fundamentally active process. In humans and other foveated species, many functions, including acuity, are not uniform across the visual field, but deteriorate with increasing distance from the foveola, the tiny rod-free region of the retina where cones are most densely packed. This strateg...

متن کاملNon-linear retinal processing supports invariance during fixational eye movements
Fixational eye movements can rapidly shift the retinal image, but typically remain unnoticed. We identify and simulate a model mechanism for the suppression of erroneous motion signals under fixational eye movements. This mechanism exploits the non-linearities common to many classes of large retinal ganglion cells in the mammalian retina, and negates the need for extra-retinal signals or explic...
متن کاملBinocular eye movements evoked by self-induced motion parallax.
Perception often triggers actions, but actions may sometimes be necessary to evoke percepts. This is most evident in the recovery of depth by self-induced motion parallax. Here we show that depth information derived from one's movement through a stationary environment evokes binocular eye movements consistent with the perception of three-dimensional shape. Human subjects stood in front of a dis...
