We investigate the feasibility of an optoelectronic edge detection system, using a diffusion neural network. The diffusion neural network performs the Gaussian operation efficiently by means of the diffusion process. We apply this in producing the difference-of-two-Gaussians function, which can detect the intensity changes of an image. This system is composed of a spatial light modulator, a two-dimensional image sensor array, and a computer. The processing of the system can be done at a rate of 30 frames/s, making it potentially applicable to systems that require edge detection of an image in real time.
