This is a Demonstration of the ability of 5-neighbor two-dimensional cellular automata to detect simple features. A rule and its rotated counterpart analyze the array at the left for horizontal and vertical characteristics. The panels at the right show the "activations" or percentage black at each evaluation step. The number to the right is the integral of the activation graph, or the combined activations of all evaluation steps.
