Good continuation affects visual detection

An Unsupervised Algorithm for Detecting Good Continuation in Dot Patterns

In this article we describe an algorithm for the automatic detection of perceptually relevant configurations of ‘good continuation’ of points in 2D point patterns. The algorithm is based on the ‘a contrario’ detection theory and on the assumption that ‘good continuation’ of points are locally quasi-symmetric. The algorithm has only one critical parameter, which controls the number of false dete...

A unified account of tilt illusions, association fields, and contour detection based on elastica

As expressed in the Gestalt law of good continuation, human perception tends to associate stimuli that form smooth continuations. Contextual modulation in primary visual cortex, in the form of association fields, is believed to play an important role in this process. Yet a unified and principled account of the good continuation law on the neural level is lacking. In this study we introduce a po...

Measuring the visual salience of alignments by their non-accidentalness

Quantitative approaches are part of the understanding of contour integration and the Gestalt law of good continuation. The present study introduces a new quantitative approach based on the a contrario theory, which formalizes the non-accidentalness principle for good continuation. This model yields an ideal observer algorithm, able to detect non-accidental alignments in Gabor patterns. More pre...

The Perceptual Organization of Visual Flows

The Perceptual Organization of Visual Flows Ohad Ben-Shahar 2003 Locally parallel dense patterns visual flows define a perceptually coherent structure of particular significance to perceptual organization. Geometrically, it is argued that a proper way to investigate these structures requires the frame field approach from differential geometry, a study that leads to the notion of visual flow cur...
