Perceptual grouping for generic recognition
International Journal of Computer Vision, 1996We address the problem of recognition of generic objects from a single intensity image. This precludes the use of purely geometric methods which assume that models are geometrically and precisely designed. Instead, we propose to use descriptions in terms of features and their qualitative geometric relationships.

Regularity‐based Perceptual Grouping
Computational Intelligence, 1997This paper investigates perceptual grouping from a logical point of view, defining a grouping interpretation as a particular kind of logical expression, and then developing an explicit inference theory in terms of such expressions. First, a regularity‐based interpretation language is presented, in which an observed configuration is characterized in ...

Proceedings of the 2013 ACM international conference on Interactive tabletops and surfaces, 2013
Modifying a digital sketch may require multiple selections before a particular editing tool can be applied. Especially on large interactive surfaces, such interactions can be fatiguing. Accordingly, we propose a method, called Suggero, to facilitate the selection process of digital ink. Suggero identifies groups of perceptually related drawing objects.

Using perceptual grouping for object group selection
CHI '06 Extended Abstracts on Human Factors in Computing Systems, 2006Modern graphical user interfaces support the direct manipulation of objects and efficient selection of objects is an integral part of this user interface paradigm. For the selection of object groups most systems implement only rectangle selection and shift-clicking.

Typical perceptual organization in autism: Perceptual grouping and spatial distortion
Autism Research, 2019The extensive literature on global–local processing in people with autism spectrum disorder (ASD) has recently shifted from arguing for a processing impairment among those with ASD to positing an attenuated preference for global processing. One suggestion is that the fast extraction of the global gist is less efficient in ASD, in contrast to the ...

An Embodied Approach to Perceptual Grouping
2004 Conference on Computer Vision and Pattern Recognition Workshop, 2005This paper presents a new embodied approach for object segmentation by a humanoid robot. It relies on interactions with a human teacher that drives the robot through the process of segmenting objects from arbitrarily complex, non-static images. Objects from a large spectrum of different scenarios were successfully segmented by the proposed algorithms.
