Perceptual organization based on temporal dynamics
نویسندگان
چکیده
A gure-ground segregation network is proposed based on a novel boundary pair representation. Nodes in the network are boundary segments obtained through local grouping. Each node is excitatorily coupled with the neighboring nodes that belong to the same region, and inhibitorily coupled with the corresponding paired node. Gestalt grouping rules are incorporated by modulating connections. The status of a node represents its probability being gural and is updated according to a di erential equation. The system solves the gure-ground segregation problem through temporal evolution. Di erent perceptual phenomena, such as modal and amodal completion, virtual contours, grouping and shape decomposition are then explained through local di usion. The system eliminates combinatorial optimization and accounts for many psychophysical results with a xed set of parameters.

Explanation of affecting factors on Perceptual organization pattern of district 1 of contemporary Tehran based on pattern language theory
District 1 of Tehran had experienced many changes during past few decades and much of these changes, had included few tangible matters, and never considered public’s concept of urban system pattern. The present study, tried to explain pattern language system of district 1 of Tehran, based Christopher Alexander’s theory of pattern language and adapt this theory to public’s concepts. This purpose...
متن کاملTemporal Dynamics of Auditory and Visual Bistability Reveal Common Principles of Perceptual Organization
When dealing with natural scenes, sensory systems have to process an often messy and ambiguous flow of information. A stable perceptual organization nevertheless has to be achieved in order to guide behavior. The neural mechanisms involved can be highlighted by intrinsically ambiguous situations. In such cases, bistable perception occurs: distinct interpretations of the unchanging stimulus alte...
متن کاملA Systems Dynamics Model for Project Management systems of Project-Based Organization
It is obvious that the success of a project-based organization is dependent on its projects. A variety of tools such as the project excellence model, project management maturity models, the earned value method, have been developed in this regard, but there are still delays in projects because the projects have dynamic nature with non-linear relationships and feedback processes during the projec...
متن کاملAperiodic Dynamics and the Self-Organization of Cognitive Maps in Autonomous Agents
Aperiodic dynamics are known to be essential in the formation of perceptual mechanisms and representations in biological brains. Complex systems concepts are helping us to understand the properties of nonlinear systems that are fundamental for the emergence of complex spatio-temporal patterns in natural and biological systems. Advances in neuroscience and computational neurodynamics are applyin...
متن کاملSynchronization: The Computational Currency ofCognition
Spatiotemporal codes, such as synchronization of neuronal activity, offer significant computational advantages over traditional rate codes, and our recent simulation studies suggest a role for synchronization in a broad range of cognitive processes, from contour detection to associative memory. We suggest that synchronization mediates Gestalt-based perceptual organization in striate cortex, and...
