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 ...

Motion aware motion invariance [PDF]
2014 IEEE International Conference on Computational Photography (ICCP), 2014 We 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.

Publisher Summary This chapter provides a expression for the understanding of average speed. Direction of motion does not enter into the concept of speed. It also illustrates a distance-time graph for better interpretation and in such a graph a straight line represents motion with constant speed.

Proceedings of the 29th annual conference on Computer graphics and interactive techniques, 2002
In this paper we present a novel method for creating realistic, controllable motion. Given a corpus of motion capture data, we automatically construct a directed graph called a motion graph that encapsulates connections among the database. The motion graph consists both of pieces of original motion and automatically

Motion estimation of micro-motion targets with translational motion
IET International Radar Conference 2015, 2015This paper models the echo returned from a micro-motion target with translational motion as the hybrid sinusoidal frequency-modulated and polynomial-phase signal (SinFM-PPS). We decouple the SinFM component from the PPS one, relying on the properties of the multi-lag high-order ambiguity function (ml-HAF), then employ the time-frequency distribution ...

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 Perception in Motion Pictures
1980Historians and theorists of the motion picture who have felt obliged to provide some explanation of how the illusion of motion on the screen is perceived have, almost without exception, relied upon a phenomenon they have termed ‘persistence of vision’. The notion is ubiquitous in film literature.

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.

Motion Stereo—Longitudinal Motion
1992Longitudinal motion stereo sinfers depth information from a forward or backward motion, and consequently is particularly useful in autonomous robot navigation applications. Most existing algorithms have some problems associated with the location of the FOE, and with the camera and surface orientations.

PATHS OF SEEN MOTION AND MOTION AFTEREFFECT
Perceptual and Motor Skills, 1966When two small light spots moved successively and independently in straight lines, the apparent path of the second light was seen as curving in direction opposite to that of the motion of the first light. The effect of the first motion on the apparent path of the second light was considered a motion aftereffect.
