Associative grouping: Perceptual grouping of shapes by association [PDF]
Attention, Perception, and Psychophysics, 2009 Perceptual grouping is usually defined by principles that associate distinct elements by virtue of image properties, such as proximity, similarity, and occurrence within common regions. What role does learning play in forming a perceptual group? This study provides evidence that learning of shape associations leads to perceptual grouping. Subjects were

A Group Test of Perceptual Acuity
Perceptual and Motor Skills, 1967A continuing need in psychological appraisal is for instruments free of educational, linguistic, or experiential bias. The perception of form and geometric properties of figures (e.g., length, width, and area) is a universal phenomenon and hence an inviting domain for study.

Preattentive Vision and Perceptual Groups
Perception, 1990Recent evidence suggests that preattentive processing may not be limited to the analysis of simple stimulus features as previously suggested. To explore this idea a visual search task was used to test whether the shapes of several perceptual groups can be processed in parallel. Textured displays that give rise to strong perceptual grouping were used to

Perceptual Grouping in Audition
Perception, 1977The present experiments evaluated the effect of relative frequency as a determinant of the figure-ground organization of sequences of auditory tones. Observers counted sequences of 20 ms tones that were presented at the same frequency or that alternated between two different frequencies.

The term perceptual grouping is associated with classical principles such as similarity and proximity. This article reports induced perceptual grouping, a phenomenon that occurs when placement of a uniform set of items near a structured set induces grouping within the otherwise uniform set.

Object discovery with perceptual grouping
2008 15th IEEE International Conference on Image Processing, 2008We propose an iterative method for discovering objects in images. In each iteration, the current estimate of the layout is processed by a sequence of perceptual grouping rules. Perceptual grouping appears to be the basis of visual organization of human. It is concerned with the problem of the formation of wholes from parts.

Neuroscience Letters, 2005 We investigated the extent to which intramodal visual perceptual grouping influences the multisensory integration (or grouping) of auditory and visual motion information.

Grouping Strategies in Induced Perceptual Grouping
Vision ResearchInduced grouping refers to the influence of a perceived group of elements on the grouping of another set of elements that cannot be explained by other grouping principles. Vickery (2008) first highlighted this phenomenon and, despite convincing demonstrations of this principle, seems to be the only direct study.

A Probabilistic Approach to Perceptual Grouping
Computer Vision and Image Understanding, 1996We present a general framework for determining probability distributions over the space of possible image feature groupings. The framework can be used to find several of the most probable partitions of image features into groupings, rather than just returning a single partition of the features as do most feature grouping techniques.

Integration of perceptual grouping and depth
Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002Different data acquisition methods are tailored at extracting particular characteristics from a scene and by combining their results a more robust scene description can be created. A method to fuse perceptual groupings extracted from color-based segmentation and depth information from stereo using supervised classification is presented.
