Developmental differences in the perception of naturalistic human movements
Frontiers in Human Neuroscience, 2023 IntroductionIt is widely believed that we are more attentive towards moving versus static stimuli. However, the neural correlates underlying the perception of human movements have not been extensively investigated in ecologically valid settings, nor has ...

Self-Supervised Video Representation Learning with Motion-Contrastive Perception [PDF]
arXiv, 2022 Visual-only self-supervised learning has achieved significant improvement in video representation learning. Existing related methods encourage models to learn video representations by utilizing contrastive learning or designing specific pretext tasks.

The efficiency of biological motion perception [PDF]
Journal of Vision, 2005 Humans can readily perceive biological motion from point-light (PL) animations, which create an image of a moving human figure by tracing the trajectories of a small number of light points affixed to a moving human body. We have applied ideal observer analysis to a standard biological motion discrimination task involving either full-figure or PL ...

Neural coincidence detection strategies during perception of multi-pitch musical tones [PDF]
arXiv, 2020 Multi-pitch perception is investigated in a listening test using 30 recordings of musical sounds with two tones played simultaneously, except for two gong sounds with inharmonic overtone spectrum, judging roughness and separateness as the ability to tell the two tones in each recording apart.

On the role of Lip Articulation in Visual Speech Perception [PDF]
arXiv, 2022 Generating realistic lip motion from audio to simulate speech production is critical for driving natural character animation. Previous research has shown that traditional metrics used to optimize and assess models for generating lip motion from speech are not a good indicator of subjective opinion of animation quality.

Saccadic Suppression of Displacement Does Not Reflect a Saccade-Specific Bias to Assume Stability
Vision, 2019 Across saccades, small displacements of a visual target are harder to detect and their directions more difficult to discriminate than during steady fixation.

Perception-Aware Motion Planning via Multiobjective Search on GPUs [PDF]
arXiv, 2017 In this paper we describe a framework towards computing well-localized, robust motion plans through the perception-aware motion planning problem, whereby we seek a low-cost motion plan subject to a separate constraint on perception localization quality.

Capture Uncertainties in Deep Neural Networks for Safe Operation of Autonomous Driving Vehicles [PDF]
arXiv, 2021 Uncertainties in Deep Neural Network (DNN)-based perception and vehicle's motion pose challenges to the development of safe autonomous driving vehicles. In this paper, we propose a safe motion planning framework featuring the quantification and propagation of DNN-based perception uncertainties and motion uncertainties.

Asymmetry in the perception of motion-in-depth
Vision Research, 2004 We investigated the anisotropic responses between the detection of motion toward and motion away from the observers with expanding/contracting shaded circles. Our experiments followed visual search paradigm with two exceptions: (1) the stimulus presentation time was fixed for 300 ms and (2) the mean error rates were adopted as a dependent variable.

Adaptation in motion perception: Alteration of induced motion [PDF]
Perception & Psychophysics, 1978 Prolonged exposure to a condition that causes induced motion was found to diminish this effect. The extent of a horizontal induced motion was measured by obtaining estimates of the direction of the apparent oblique path that resulted when a spot was visible on a horizontally moving pattern and was therefore in horizontal induced motion and, at the same
