Grouping by Proximity in Haptic Contour Detection
We investigated the applicability of the Gestalt principle of perceptual grouping by proximity in the haptic modality. To do so, we investigated the influence of element proximity on haptic contour detection. In the course of four sessions ten participants performed a haptic contour detection task in which they freely explored a haptic random dot display that contained a contour in 50% of the t...
متن کاملContour grouping: closure effects are explained by good continuation and proximity
Previous experimental studies have provided evidence that closed contours are easier to detect than open contours in random-element displays, and previous theoretical studies have shown that these effects might be explained by an active neural mechanism (e.g., a "reverberating neural circuit") sensitive to closure. To test this hypothesis, detection thresholds were measured in five experiments ...
متن کاملOptimal Contour Closure by Superpixel Grouping
Detecting contour closure, i.e., finding a cycle of disconnected contour fragments that separates an object from its background, is an important problem in perceptual grouping. Searching the entire space of possible groupings is intractable, and previous approaches have adopted powerful perceptual grouping heuristics, such as proximity and co-curvilinearity, to manage the search. We introduce a...
متن کاملOn the lawfulness of grouping by proximity.
The visual system groups close things together. Previous studies of grouping by proximity have failed to measure grouping strength or to assess the effect of configuration. We do both. We reanalyze data from an experiment by Kubovy and Wagemans (1995) in which they briefly presented multi-stable dot patterns that can be perceptually organized into alternative collections of parallel strips of d...
متن کاملQualifying Exam Contour Grouping
In this paper, I review the contour grouping approaches towards segmentation of images. Classifying the existing literature into local and global methods, I show how the grouping methods have improved over time, moving from local to global and from heuristic to probabilistic. Requirements for performance evaluation of grouping algorithms are also discussed.
