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.

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.

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).

[1990] Proceedings Third International Conference on Computer Vision, 1991
The author compares the photometric effects of motion (which is defined as the variation of a point's imaged intensity as a consequence of motion) and the geometric effects of motion (which is defined as the variation in projected surface geometry as a consequence of motion).

Motion estimation with integrated motion models
Proceedings of the 42nd annual Southeast regional conference, 2004Conventional motion estimation algorithms rely on motion vectors characterizing translations and thus have limitations in capturing transformations of objects in video scenes such as scaling, rotations and deformations. In this paper, we introduce integrated motion models based on the Lie derivatives to improve the motion estimation accuracy.

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.

Stereo-motion with stereo and motion in complement
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2000This paper presents a new approach of combining stereo vision and dynamic vision with the objective of retaining their advantages and removing their disadvantages. It is shown that, by assuming affine cameras, the stereo correspondences and motion correspondences, if organized in a particular way in a matrix, can be decomposed into: the 3D structure of

The influence of background motion on the motion aftereffect
Vision Research, 1984The motion aftereffect caused by adaptation to moving bars is visible in a stationary test pattern consisting of static visual noise (texture). The aftereffect resulting from adaptation to moving bars presented on a background of texture is highly dependent on the direction and velocity of motion of the background during adaptation, and less dependent ...

Motion over the Retina and the Motion Aftereffect
Perception, 1992The motion aftereffect (MAE) was measured with retinally moving vertical gratings positioned above and below (flanking) a retinally stationary central grating (experiments 1 and 2). Motion over the retina was produced by leftward motion of the flanking gratings relative to the stationary eyes, and by rightward eye or head movements tracking the moving (
