Some dimensions do coincide with "real" perceptual and response features, such as spatial localisation, movement direction, and opticalflow. In short, by actively rotating the eye, the observer can recover the ambient opticalflow field from image motion. Because we have frontal eyes, our field of view is restricted to a small portion of the opticalflow. However, when an observer looks around, sampling different portions of the ambient opticalflow, the image pattern on the retina (retinal flow) changes. Direction of self-motion is perceived from opticalflow. Based on the arguments presented here, active rotation of the eyes is essential for extracting the self-movement information contained in opticalflow. The opticalflow methods currently under investigation for this purpose are far more computationally intensive and less robust than the path planner and remain the major hurdle to be overcome. I present a case in which only with the active sampling of the ambient opticalflow field can observers extract the requisite information for the control of locomotion. Height is determined from the speed of the craft and measuring of opticalflow. The use of velocity fields and an opticalflow allows us to deform the image in a sequence of small steps and the mapping is known to be a diffeomorphism. Motion stereo and opticalflow techniques are used to update a map of the environment. Perception of circular heading from opticalflow. Wertheim points out that when exposed to opticalflow rotating around an axis parallel to earth gravity, experimental participants experience an illusion that they are rotating relative to the earth. He studied the concept of opticalflow (later published as part of his theory of affordance). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
