Biologically Inspired Motion Encoding for Robust Global Motion Estimation [PDF]

IEEE Transactions on Image Processing, 2017
The growing use of cameras embedded in autonomous robotic platforms and worn by people is increasing the importance of accurate global motion estimation (GME). However, existing GME methods may degrade considerably under illumination variations. In this paper, we address this problem by proposing a biologically-inspired GME method that achieves high ...

The domestic chick as an animal model of autism spectrum disorder: building adaptive social perceptions through prenatally formed predispositions

Frontiers in Neuroscience
Equipped with an early social predisposition immediately post-birth, humans typically form associations with mothers and other family members through exposure learning, canalized by a prenatally formed predisposition of visual preference to biological ...

Dilation and Constriction of Subjective Time Based on Observed Walking Speed

Frontiers in Psychology, 2018
The physical properties of events are known to modulate perceived time. This study tested the effect of different quantitative (walking speed) and qualitative (walking-forward vs.

Using Surface-Motions for Locomotion of Microscopic Robots in Viscous Fluids [PDF]

, 2014
Microscopic robots could perform tasks with high spatial precision, such as acting in biological tissues on the scale of individual cells, provided they can reach precise locations.

Crowding of biological motion stimuli

Journal of Vision, 2013
It is difficult to identify a target in the peripheral visual field when it is flanked by distractors. In the present study, we investigated this "crowding" effect for biological motion stimuli. Three walking biological motion stimuli were presented horizontally in the periphery with various distances between them, and observers reported the walking ...

Deep learning cardiac motion analysis for human survival prediction [PDF]

, 2018
Motion analysis is used in computer vision to understand the behaviour of moving objects in sequences of images. Optimising the interpretation of dynamic biological systems requires accurate and precise motion tracking as well as efficient ...

Something in the way they move: characteristics of identity present in faces, voices, body movements, and actions

Frontiers in Psychology
The recognition of familiar individuals relies not only on static features of the person but also on dynamic characteristics unique to each person’s movements.

Postural Stabilization Strategies to Motor Contagion Induced by Action Observation Are Impaired in Parkinson’s Disease

Frontiers in Neurology, 2018
Postural reactions can be influenced by concomitant tasks or different contexts and are modulated by a higher order motor control. Recent studies investigated postural changes determined by motor contagion induced by action observation (chameleon effect)

Amblyopic perception of biological motion

Journal of Vision, 2008
Although a number of low-level visual deficits in amblyopia have been identified, it is still unclear to what extent these deficits extend throughout the visual processing hierarchy. Biological motion perception can be a useful measure of local and global visual processing since the point-light stimuli that are often used to study this ability carry ...

Perception of animate motion in dogs

Frontiers in Psychology
Various motion cues can lead to the perception of animacy, including (1) simple motion characteristics such as starting to move from rest, (2) motion patterns of interactions like chasing, or (3) the motion of point-lights representing the joints of a ...
