Two principles of perceptual organization have been proposed. The likelihood principle,
following HL E von Helmholtz (1910/1962), proposes that perceptual organization is chosen …

We describe a method to automatically find gradient thresholds to separate edge from
nonedge pixels. A statistical model that is the weighted sum of two gamma densities …

The proximity compatibility principle (PCP) proposes that visually unitary configurations of
data values, such as object displays, will support information integration better than will …

Detection of vertical bilateral symmetry has previously been studied in patterns composed of
black or white dots on a grey background under four conditions:(a) same contrast (black or …

The global precedence hypothesis was investigated in a series of experirnents by
considering the effects of eccentricity and size and their possible interaction on the speed of …

Four experiments were conducted to investigate whether variations in orientation that
profoundly affect the ability to imagine rotations also affect the ability to imagine projective …

Wir verstehen als Wortbedeutung die Beziehung, die Wörter mit Konzepten eingehen
(Herrmann, 1994). Das kognitive System des Menschen verfügt unter anderem über …

Publisher Summary Structures in the environment are recognized without any effort,
although these structures are always embedded in a variety of visual contexts. Visual stimuli …

In the enhancement/thresholding method of edge detection, the gradient values of pixels
exceeding a certain threshold are designated as edge pixels. However, selecting a …

In our paper we discuss the Berlin Gestalt theory, its relation to modelling with artificial
neural networks and ask if Gestalt theory may serve as a paradigm for future research on …
