scripts default iconDiffusive filling-in (Scripts) Publisher's description

This software has been realized by Gennady Livitz at the CNS Technology Lab at Boston University

This software has been realized by Gennady Livitz at the CNS Technology Lab at Boston University (My Webpage). The main author of this software is Gennady Livitz. The package contains a MATLAB implementation of diffusive filing-in model. The demo simulation is based on Craik-O'Brien-Cornsweet Effect(COCE). The package provides GUI interface to control luminance of COCE stimulus components which have impact on the model's output. The software can be run from matlab command line by typing Filling_in at the prompt. Necessary documentation as well as source code is provided at http://techlab.bu.edu/resources/synapse_vi...ng_in/#download.

Present implementation of diffusive filling-in model demonstrates dynamics of neural signal spreading on the example of Craik-O'Brien-Cornsweet Effect. Filling-in process is implemented as a set of non-linear differential equations that control spreading of the activity of the Feature Contour System signals (brightness, color) within the image segments defined by the Boundary Contour System signals. The demo example simulates 1D filling-in process and allows the user to see the impact of luminance contrast in the COCE configuration on the output of the present implementation of diffusive filling-in model.
