Adversarially Robust Video Perception by Seeing Motion [PDF]
arXiv, 2022 Despite their excellent performance, state-of-the-art computer vision models often fail when they encounter adversarial examples. Video perception models tend to be more fragile under attacks, because the adversary has more places to manipulate in high-dimensional data. In this paper, we find one reason for video models' vulnerability is that they fail

Towards Integrated Perception and Motion Planning with Distributionally Robust Risk Constraints [PDF]
arXiv, 2020 Safely deploying robots in uncertain and dynamic environments requires a systematic accounting of various risks, both within and across layers in an autonomy stack from perception to motion planning and control. Many widely used motion planning algorithms do not adequately incorporate inherent perception and prediction uncertainties, often ignoring ...

Perception of Motion and Architectural Form: Computational Relationships between Optical Flow and Perspective [PDF]
arXiv, 2011 Perceptual geometry refers to the interdisciplinary research whose objectives focuses on study of geometry from the perspective of visual perception, and in turn, applies such geometric findings to the ecological study of vision. Perceptual geometry attempts to answer fundamental questions in perception of form and representation of space through ...

Multisensory contributions to the perception of motion
Neuropsychologia, 2003 The ability to process motion is crucial for coherent perception and action. While the majority of studies have focused on the unimodal factors that influence motion perception (see, for example, the other chapters in this Special Issue), some researchers have also investigated the extent to which information presented in one sensory modality can ...

The effect of motion acceleration on displacement of continuous and staircase motion in the frontoparallel plane [PDF]
Psihološka Obzorja, 2002 If a moving target suddenly disappears, memory for the final location of the target is displaced forward in the direction of motion. This displacement depends on higher order motion regularities (e.g., velocity, acceleration), and so a consideration of ...

Atypical integration of motion signals in Autism Spectrum Conditions.
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 ...

Towards Computational Models and Applications of Insect Visual Systems for Motion Perception: A Review [PDF]
arXiv, 2019 Motion perception is a critical capability determining a variety of aspects of insects' life, including avoiding predators, foraging and so forth. A good number of motion detectors have been identified in the insects' visual pathways. Computational modelling of these motion detectors has not only been providing effective solutions to artificial ...

Speed Biases With Real-Life Video Clips
Frontiers in Integrative Neuroscience, 2018 We live almost literally immersed in an artificial visual world, especially motion pictures. In this exploratory study, we asked whether the best speed for reproducing a video is its original, shooting speed.

Pattern Motion Processing by MT Neurons
Frontiers in Neural Circuits, 2019 Based on stimulation with plaid patterns, neurons in the Middle Temporal (MT) area of primate visual cortex are divided into two types: pattern and component cells. The prevailing theory suggests that pattern selectivity results from the summation of the
