Motion aware motion invariance
2014 IEEE International Conference on Computational Photography (ICCP), 2014We address motion de-blurring using a computational camera that captures an image while the stabilizing optical element moves in a modified Canon IS lens. Our work builds on that of Levin et al. [11], who introduce parabolic motion as a means of achieving invariance to unknown subject velocity in an a priori known direction.

Motion compensation of motion vectors
Proceedings., International Conference on Image Processing, 2002Motion compensation of image data has long been used for video compression. "Meta-motion" compensation, or motion compensation of motion vectors is presented as a new approach to data compression useful in very low bit rate (VLB) applications. Whereas present motion coding simply takes advantage of temporal redundancies among images, this new ...

Motion contrast and motion integration
Vision Research, 1993When a moving aperture contains a drifting grating, the perception of aperture movement is strongly affected by the grating movement. We have studied this interaction, using a moving circular patch of sinusoidal grating matched to the background in mean luminance.

MotionBERT: A Unified Perspective on Learning Human Motion Representations
IEEE International Conference on Computer Vision, 2022We present a unified perspective on tackling various human-centric video tasks by learning human motion representations from large-scale and heterogeneous data resources.

Motion detectors and motion segregation
Spatial Vision, 1995The response of motion detectors necessarily confound image velocity with image structure. In particular, even a rigidly moving image (with a uniform velocity field) will give rise to non-uniform detector responses. A mathematical framework has been proposed on how to intrinsically compare motion detectors' responses so that their differences will ...

Journal of the Acoustical Society of America, 2015
The acoustic cues to auditory space are referenced to the head which moves through the world, itself composed of moving sources so that our sensation convolves source with self- motion. With the head still, velocity discrimination, a perceptual process, is related to static acuity via the minimum audible movement angle (MAMA).

Heart motion simulator for motion compensation
2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011A robotic heart motion simulator (HMS) is developed at DLR (German Aerospace Center) to accurately simulate real translational motions of a mechanically stabilized beating heart in a lab environment. This simulator is part of the DLR scenario for motion compensation on the beating heart.

Learning Lane Graph Representations for Motion Forecasting
European Conference on Computer Vision, 2020We propose a motion forecasting model that exploits a novel structured map representation as well as actor-map interactions. Instead of encoding vectorized maps as raster images, we construct a lane graph from raw map data to explicitly preserve the map ...

Motion integration during motion aftereffects
Trends in Cognitive Sciences, 2002The perceived global motion of a stimulus depends on how its different local motion-direction vectors are distributed in space and time. When they are explicitly co-localized, as in the case of locally paired motion, competitive motion integration mechanisms produce a unitary global motion direction determined by their vector average.

Brownian Motion in a Field of Force and the Diffusion Model of Chemical Reactions
Master of Modern Physics, 1940A particle which is caught in a potential hole and which, through the shuttling action of Brownian motion, can escape over a potential barrier yields a suitable model for elucidating the applicability of the transition state method for calculating the ...
