Computing with Biologically Inspired Neural Oscillators: Application to Colour Image Segmentation

Figure 11

A grid (network) of competitive self-organising locally excitatory globally inhibitory neural oscillators. Each neural oscillator is connected to its four neighbours through excitatory synapses and receives inhibition from a global inhibitor. The latter helps create competition between neurons that belong to a single object (synchronised) and other neurons which belong to different objects (desynchronised). Only the coupling between oscillators 𝑥_𝑖 and 𝑥_𝑗 has been highlighted; the connections between each neuron and other neighbours are not shown for simplicity.
