Part-based representations allow for recognition that is robust in the presence of occlusion,
movement, growth, and deletion of portions of an object, and play an important role in …

We examined the grouping of line segments into unitary shapes and attempted to identify
procedures to diagnose when such grouping is taking place. Previous research has …

Underlying recognition is an organization of objects and their parts into classes and
hierarchies. A representation of parts for recognition requires that they be invariant to rigid …

Human vision organizes object shapes in terms of parts and their spatial relationships.
Converging experimental evidence suggests that parts are computed rapidly and early in …

A distinction has previously been proposed between global properties, defined by their
position in the hierarchical structure of the stimulus, and wholistic/configural properties …

Subjects judged whether two marks placed at different positions along a curved contour
were physically the same. When targets were separated by a concave curvature extremum …

This article develops a view of shape representation both in visual experience and in
subpersonal visual processing. The view is that, in both cases, shape is represented in a …

The nature of the psychological processes that underlie the Gestalt principles of grouping by
proximity and grouping by similarity is examined. Similarity was defined relative to the …

Seven experiments investigated whether part connectedness would facilitate the perception
of spatial relations among object parts. Experiments 1–4 showed that objects composed of …

Whether objects are represented as a collection of parts whose relations are coded
independently remains a topic of ongoing discussion among theorists in the domain of …
