This simple autoassociative Hopfield net can discriminate between two images, even at a fairly low signal to noise ratio (about a decade of attenuation in this case), with about 95% success rate at this SNR. Net size is 100x100; connections are randomly chosen and asymmetrical, and connectivity is 7. State change is stochastic.

Test yourself: after watching the video, pause at 0:00 and 0:33 and see if you can tell which is which.
