The development of motion sickness appears intimately related to the visual system. The Sensory Rearrangement Theory states that situations which promote motion sickness are characterized by a condition in which the motion signals transmitted by the eyes, vestibular system, and the nonvestibular proprioceptors are at variance as to what was expected ...

Proceedings CVPR '88: The Computer Society Conference on Computer Vision and Pattern Recognition, 2003
A fast tracking algorithm is used to determine displacements of points (pixels) on object surfaces between frames, a sequence of image frames representing a time-varying scene. The displacement is represented by a four-dimension vector whose elements are two-dimensional translation, rotation, rotational angle on the x-y plane, and scaling factor (zoom ...

Human Vision Favors Centrifugal Motion
Perception, 1980Reaction times to motion onset were measured for targets in the peripheral field. Horizontal motion away from fixation evoked faster reactions than did motion toward fixation. The difference between motion toward fixation and motion away from fixation (i) increases with stimulus eccentricity, (ii) is not found when motion is along a vertical axis, and

Neuromodulation of insect motion vision
Journal of Comparative Physiology A, 2019Insects use vision to choose from a repertoire of flexible behaviors which they perform for survival. Decisions for behavioral plasticity are achieved through the neuromodulation of sensory processes, including motion vision. Here, we briefly review the anatomy of the insect motion vision system. Next, we review the neuromodulatory influences on motion

IFAC Proceedings Volumes, 1990
We present a method for the recovery of environment structure and camera motion from a sequence of images taken by a camera in motion. Unlike previous approaches, our method of Dynamic Motion Vision explicitly models the perceived temporal variation of the scene structure in the form of a dynamical system.

Motion-deblurring in human vision
Nature, 1989If photographs are taken of moving objects at slow shutter speeds the images of the objects are blurred. In human vision, however, we are not normally conscious of blur from moving objects despite the fact that the temporal response of the photoreceptors is sluggish.

Abstract Visual perception seems effortless to us, yet it is the product of elaborate signal processing in intricate brain circuits. Apart from vertebrates, arthropods represent another major animal group with sophisticated visual systems in which the underlying mechanisms can be studied.

[1992] Proceedings. 11th IAPR International Conference on Pattern Recognition, 2003
Earlier, the author (1991) introduced a direct method called fixation for the recovery of shape and motion in the general case. The method uses neither feature correspondence nor optical flow. Instead, it directly employs the spatio-temporal gradients of images brightnesses.

Motion vision: Fish swimming to see
Current Biology, 2023Self-motion generates optic flow, a visual motion signal used by many organisms for navigation and self-stabilization. A new study quantitatively demonstrates how environmental structure and current behavioral state explain the spatial biases observed in zebrafish optomotor responses.

Proceedings., IEEE International Conference on Robotics and Automation, 2002
A method is presented for estimating the structure of a scene and the motion of an observer relative to the scene from a sequence of images. Two key features distinguish this method from previous solutions to this problem: no computation of optical flow is required, which leads to considerable speedup, and a Kalman filtering algorithm takes advantage ...
