ReLU, Sparseness, and the Encoding of Optic Flow in Neural Networks. [PDF]
Sensors (Basel)Accurate self-motion estimation is critical for various navigational tasks in mobile robotics. Optic flow provides a means to estimate self-motion using a camera sensor and is particularly valuable in GPS- and radio-denied environments. The present study

Sensor-Guided Optical Flow [PDF]
2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021 This paper proposes a framework to guide an optical flow network with external cues to achieve superior accuracy either on known or unseen domains. Given the availability of sparse yet accurate optical flow hints from an external source, these are injected to modulate the correlation scores computed by a state-of-the-art optical flow network and guide ...

Optic flow detection is not influenced by visual-vestibular congruency. [PDF]
PLoS ONE, 2018 Optic flow patterns generated by self-motion relative to the stationary environment result in congruent visual-vestibular self-motion signals. Incongruent signals can arise due to object motion, vestibular dysfunction, or artificial stimulation, which ...

A functional architecture of optic flow in the inferior parietal lobule of the behaving monkey. [PDF]
PLoS ONE, 2007 The representation of navigational optic flow across the inferior parietal lobule was assessed using optical imaging of intrinsic signals in behaving monkeys.

The effect of vection on the use of optic flow cues. [PDF]
R Soc Open SciWhen we move objects move past us in a relative pattern of motion referred to as optic flow. Modulations in optic flow can impact both our perception of self-motion (e.g.

Functional correlates of optic flow motion processing in Parkinson’s disease
Frontiers in Integrative Neuroscience, 2014 The visual input created by the relative motion between an individual and the environment, also called optic flow, influences the sense of self-motion, postural orientation, veering of gait, and visuospatial cognition.

Scholarpedia, 2013 Optic flow refers to the image motion of the environment projected on the retina during our movement in the world. The term was first coined by James J. Gibson and played a key role in the development of the ecological approach to visual perception, an approach that emphasizes studying human perception in the natural environment rather than in a ...

Early Postural EMG Dynamics During Optic Flow: Effects of Time, Velocity, Retinal Location and Laterality. [PDF]
Brain SciBackground/Objectives: Optic-flow velocity is known to influence postural sway, whereas corresponding electromyographic (EMG) effects may be difficult to detect when muscle activity is averaged over long stimulation periods. We therefore investigated the

Optic flow density modulates corner-cutting in a virtual steering task for younger and older adults. [PDF]
Sci RepThere is a critical need to understand how aging visual systems contribute to age-related increases in vehicle accidents. We investigated the potential contribution of age-related detriments in steering based on optic flow, a source of information known ...
