Abstract: The Emergic Cognitive Model (ECM) is a unified computational model of visual filling-in based on the Emergic Network architecture. The Emergic Network was designed to help realize systems undergoing continuous change. In this thesis, eight different filling-in phenomena are demonstrated under a regime of continuous eye movement (and under static eye conditions as well). Continue reading

Leibovitz, D. P. (2010) Lilac Chaser Illusion and Virtual Eyeballs. Talk presented at Carleton University, Ottawa, Canada. [doi: 10.13140/RG.2.1.2268.5923]
Abstract: David Leibovitz will give a live demo of his research-in-progress and discuss the nature of his research and future plans. David will demonstrate a framework, whereby a Virtual Eye is looking at the Lilac Chaser visual illusion. Currently, the implementation has a minimal cognitive component, a set of photoreceptors for the fovea, and saccadic jitter for the eye.

The Emergic Cognitive System (or ECS) is a system for embodying a developmental cognitive model in a virtual and dynamic agent that is situated in a dynamic environment using simulated real-time for non-representational information processing. This allows a zero parameter model to be tested with a wide variety of experimental paradigms covering a large contextual domain.
Historical Names: Emergic Simulation System (ESS); Emergic Vision System (EVS)

Emergic Cognitive Model
The Emergic Cognitive Model (or ECM) is a unifying cognitive model that develops genetically, i.e., based on development parameters or modeling DNA. ECM advances a single powerful theory of human cognition for explaining a variety of emergent phenomena described across experimental paradigms and academic disciplines
The unifying model has no free parameters, and its emergent behavior is commensurate with expectations in its developmental differences, as well as its interactions across a variety of environments, stimuli and situations.
Unifying modeling is guided by the principles of the Emergic Approach for progressing science. Thus, ECM is based on the Emergic Network (a computational architecture), is embodied and developed within virtual agents (persons), and situated within environments (worlds) of an Emergic Cognitive System, for non-representational real-time information processing.
Jittering retina of the Emergic Cognitive Model
Currently, the Emergic Cognitive Model supports low-level aspects of dynamic visual processing. It has a biological realistic retina (with a blind spot, a random placement of photoreceptors that grow in size beyond the fovea), and supports eye movement (including jitter) without motion blur, blinking, and object motion.
