Neural Dynamics of Motion Perception: Direction Fields, Apertures, and Resonant Grouping [PDF]
, 1992 A neural network model of global motion segmentation by visual cortex is described. Called the Motion Boundary Contour System (BCS), the model clarifies how ambiguous local movements on a complex moving shape are actively reorganized into a coherent ...

Atypical integration of motion signals in Autism Spectrum Conditions. [PDF]
PLoS ONE, 2012 Vision in Autism Spectrum Conditions (ASC) is characterized by enhanced perception of local elements, but impaired perception of global percepts. Deficits in coherent motion perception seem to support this characterization, but the roots and robustness ...

Risk Bounded Nonlinear Robot Motion Planning With Integrated Perception & Control [PDF]
arXiv, 2022 Robust autonomy stacks require tight integration of perception, motion planning, and control layers, but these layers often inadequately incorporate inherent perception and prediction uncertainties, either ignoring them altogether or making questionable assumptions of Gaussianity.

Temporoparietal encoding of space and time during vestibular-guided orientation [PDF]
, 2015 When we walk in our environment, we readily determine our travelled distance and location using visual cues. In the dark, estimating travelled distance uses a combination of somatosensory and vestibular (i.e., inertial) cues.

Illusory motion perception in blindsight [PDF]
Proceedings of the National Academy of Sciences, 2010 Motion detection is typically spared in blindsight, which results from damage to the striate cortex (area V1) of the brain that is sufficient to eliminate conscious visual awareness and severely reduce sensitivity to luminance contrast, especially for high spatial and low temporal frequencies.

Human middle temporal cortex, perceptual bias, and perceptual memory for ambiguous three-dimensional motion [PDF]
, 2010 When faced with inconclusive or conflicting visual input human observers experience one of multiple possible perceptions. One factor that determines perception of such an ambiguous stimulus is how the same stimulus was perceived on previous occasions, a ...

Dynamic evolution of motion perception
Journal of Vision, 2007 Motion is defined as a sequence of positional changes over time. However, in perception, spatial position and motion dynamically interact with each other. This reciprocal interaction suggests that the perception of a moving object itself may dynamically evolve following the onset of motion.

Recent Approaches for Perceptive Legged Locomotion [PDF]
arXiv, 2022 As both legged robots and embedded compute have become more capable, researchers have started to focus on field deployment of these robots. Robust autonomy in unstructured environments requires perception of the world around the robot in order to avoid hazards.

Cortical Dynamics of Visual Motion Perception: Short-Range and Long Range Apparent Motion [PDF]
, 1991 This article describes further evidence for a new neural network theory of biological motion perception that is called a Motion Boundary Contour System. This theory clarifies why parallel streams Vl-> V2 and Vl-> MT exist for static form and motion form ...
