Object selection in visual scene via oscillatory network with controllable coupling and self-organized performance

Abstract

An oscillatory network model with controllable coupling and self-organized synchronization-based performance was developed for image processing. The model demonstrates the following capabilities: (a) brightness segmentation of real grey-level images; (b) colored image segmentation; (c) selective image segmentation--extraction of the subset of image fragments with brightness values contained in an arbitrary given interval. An additional capability--successive selection of spatially separated fragments of a visual scene--has been achieved via further model extension. The fragment selection (under minor natural restrictions on mutual fragment locations) is based on in-phase internal synchronization of oscillator ensembles, corresponding to all the fragments, and distinct phase shifts between different ensembles.
