Optical implementation of Hartline lateral inhibition model
Changda Zhou · Acta Optica Sinica · 1992
Hartline model, discovered form neurophyeiological experiments, reveals the principle of lateral inhibition which generally exists in neural system. In this paper we propose an optoelectronic arohiteture for implementation of Hartline model in which incoherent optical convolutor and polarization encoding method used to realize the convolution operation and the representation of weight function, while subtraction operation is still performed by electronic part. Preliminary optical 2-D image edge enhancement experiment demonstrates the versatility of the network.
