Abstract In 1912, Max Wertheimer published his paper on phi motion, widely recognized as
the start of Gestalt psychology. Because of its continued relevance in modern psychology …

Most of our knowledge about the functional organization of neuronal systems is based on
the analysis of the firing patterns of individual neurons that have been recorded one by one …

How a sensory stimulus is processed and perceived depends on the surrounding sensory
scene. In the visual cortex, contextual signals can be conveyed by an extensive network of …

Human visual perception carves a scene at its physical joints, decomposing the world into
objects, which are selectively attended, tracked and predicted as we engage our …

I propose that pre-attentive computational mechanisms in primary visual cortex create a
saliency map. This map awards higher responses to more salient image locations; these …

We present an overview of various edge and line oriented approaches to contour detection
that have been proposed in the last two decades. By edge and line oriented we mean …

The human brain manages to correctly interpret almost every visual image it receives from
the environment. Underlying this ability are contour grouping mechanisms that appropriately …

Singer, 1994). The basis for this argument is that it is necessary to “tag” each visual neuron
to signify the object to which its activity relates. Each neuron therefore has to carry two …

important to introduce an important parameter. Although not often made explicit, it is …

Object contour plays an important role in fields such as semantic segmentation and image
classification. However, the extraction of contour is a difficult task, especially when the …
