Motion integration during motion aftereffects

Trends in Cognitive Sciences, 2002
The 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, 2000
This 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, 1984
The 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, 1992
The 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 (

Considerations of Self-Motion in Motion Saliency

2013 2nd IAPR Asian Conference on Pattern Recognition, 2013
Despite a number of studies of computational models of visual saliency, it is still difficult to predict where human would attend in a scene. One of the problems is the effect of self-motion on retinal images. Usually saliency is calculated with local motion signals, and high degree of saliency is found in motion components caused by self-motion. Since

Motion Analysis for Cooking Motion Recognition

2016 12th International Conference on Signal-Image Technology & Internet-Based Systems (SITIS), 2016
To construct a cooking motion model, we needed to analyze features of cooking motions. Our aim was to recognize cooking motions by tracking the motions of the joints of a cook's arms with a three-dimensional depth sensor. To recognize the motions, we needed to analyze their features of interest.

Motion verbs and memory for motion events

Cognitive Neuropsychology, 2019
Language is assumed to affect memory by offering an additional medium of encoding visual stimuli. Given that natural languages differ, cross-linguistic differences might impact memory processes. We investigate the role of motion verbs on memory for motion events in speakers of English, which preferentially encodes manner in motion verbs (e.g., driving),

PATHS OF SEEN MOTION AND MOTION AFTEREFFECT

Perceptual and Motor Skills, 1966
When 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.

Infant’s motion adaptation with animal motion

Infant Behavior and Development
We investigated motion adaptation with animal motion using optokinetic nystagmus responses in infants. Three movies depicting an animal running were presented,followed by the test random dot kinematogram. We predicted that viewing animal motions would shift OKN responses to the RDK in the opposite direction of animal motion.

Motion Induction from Biological Motion

Perception, 2003
A new type of motion illusion is described in which ambiguous motion becomes unidirectional on superimposition of a human figure walking on a treadmill. A point-light walker in profile was superimposed on a vertical counterphase grating backdrop. Eleven naïve observers judged the apparent direction of motion against the grating as left or right in a ...
