Fig. 5

a Schematic illustration of the structure of image processing array. b Processing images with short wavelengths and long wavelengths. c The realization of image attention processing with the increased of decay time. d The detected patterns of “H”, “I”, “J”, “K”, “L” letters with different wavelengths and encoding conductance of pattern with variant wavelengths. e Schematic diagram device array to realize the multiplication-accumulation operation. f Accuracy of multiplication-accumulation circuits with the increase of training epoch. g The distribution of the output accumulated current in the 5 input patterns.
