Abstract
The possibility of implementing optically a mean field annealing algorithm for nonlinear noise filtering of grey level images has been addressed. To cope with grey level images we have considered an algorithm that corresponds to a Q-state spin-Ising model. The method has been implemented by an optoelectronic feedback loop incorporating a defocusing camera, a spatial light modulator, and a frame grabber. Experimental results are reported.
