Perception, 2008
Examples of visual motion have become more and more abstract over the years, leading up to ‘third-order’ stimuli where direction is actually determined by the observer through top–down attention. But how far can this be pushed—are there motion stimuli that are yet more arbitrary and abstract?

Motion-based motion deblurring
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2004Motion blur due to camera motion can significantly degrade the quality of an image. Since the path of the camera motion can be arbitrary, deblurring of motion blurred images is a hard problem. Previous methods to deal with this problem have included blind restoration of motion blurred images, optical correction using stabilized lenses, and special cmos

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 Aftereffects and Retinal Motion
Perception, 1989Two experiments are described in which it was investigated whether the adaptation on which motion aftereffects (MAEs) are based is a response to retinal image motion alone or to the motion signal derived from the process which combines the image motion signal with information about eye movement (corollary discharge).

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.

Oberwolfach Reports, 2004
The workshop Wave Motion that took place in the period January 25–31, 2004 was devoted to the study of nonlinear wave phenomena. The modelling of waves leads to a variety of difficult mathematical issues, involving several domains of mathematics: partial differential equations, harmonic ...

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 ...
