On 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 کاملGrouping 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 کاملGrouping Based on Phenomenal Proximity.
The question was raised whether the Gestalt law of grouping by proximity is based on proximity of stimuli on the retina or perceived proximity in phenomenal space. To tease apart these 2 possibilities an earlier experiment of Corbin was repeated in which the stimulus array is tilted back into the 3rd dimension. By including a measure of constancy for the perceived distance between points it was...
متن کاملThree-dimensional spatial grouping affects estimates of the illuminant.
The brightnesses (i.e., perceived luminance) of surfaces within a three-dimensional scene are contingent on both the luminances and the spatial arrangement of the surfaces. Observers viewed a CRT through a haploscope that presented simulated achromatic surfaces in three dimensions. They set a test patch to be approximately 33% more intense than a comparison patch to match the comparison patch i...
متن کاملFeature grouping by 'relocalisation' of eigenvectors of the proximity matrix
We describe a widely applicable method of grouping or clustering image features (such as points, lines, corners, flow vectors and the like). It takes as input a "proximity matrix" H a square, symmetric matrix of dimension N (where N is the number of features). The element i,j of H is an initial estimate of the "proximity" between the ith and yth features. As output it delivers another square sy...
