a Diagram of the working process of images intersection function. Two 3 × 3-pixel patterns are input in parallel from each of the two input ports of the pixel process units. The current of each pixel serves as the output signal. b A total of 100 pairs of 3 × 3-pixel graphs are randomly generated, the signal “1” and “0” refer to −2 V and −9 V respectively. All the random patterns are expanded in the manner shown in a, the 3 × 3-pixel patterns are represented in the way of 9 × 1, and 100 groups of graphs are combined. Then the flattened input patterns serials are shown as the first and second rows. The third row shows the truth table of the flattened computing results. The red blocks and blue blocks represent the output “1” and “0” (computing results of logic AND). The fourth row is the actual output current value which is consistent with the truth table.
