Perceptual limits of common fate
We studied the perception of a coherently moving group of collinearly arranged dots ("target dots") that traveled orthogonally to their linear orientation within a background of noise dots moving in random yet straight directions at constant speed ("random-direction noise"). Using a 2-interval forced-choice task we obtained coherence thresholds equal to a signal-to-noise ratio of 1-2%. These th...
متن کاملMotion and shape in common fate
We determined how much motion coherence was needed to detect a target group of four moving dots in a dynamic visual noise (DVN) background. The lifetimes of the trajectories of the target and that of the noise dots were the same. In addition to parallel trajectories and collinear dot arrangements, divergent, convergent, or crossing trajectories and non-collinear dot arrangements were also teste...
متن کاملGeneralized common fate: grouping by common luminance changes.
A critical step toward object recognition is the segmentation of a scene into relevant regions. One of the most important cues for segmentation is that of common fate: Elements that move together are grouped together Here we describe a new instantiation of common fate, in which elements move together not through physical space, but through luminance space. Experiment I shows that when elements ...
متن کاملCommon-fate grouping as feature selection.
The visual system groups elements within the visual field that are physically separated yet similar to each other. Although grouping processes have been intensely studied for a century, the mechanisms of grouping remain elusive. We propose that a primary mechanism for grouping by common fate is attentional selection of a direction of motion. A unique prediction follows from this account: that t...
متن کاملProximity Visualization via Common Fate Luminance Changes
We introduce a new design for visualizing high dimensional data. Points in high dimensional space are often illustrated through 2D or 3D embeddings, which are often cluttered and may-be unaccessible to non-scientific audience. In our design, instead of representing data points as 2D/3D vectors, each data point is represented by a smoothly varying function of time. These smooth functions are use...
