Extended Data Fig. 1: Convolutional image processing in the molecular crystal memristor crossbar array.

a, Schematic of convolution operation between voltage vectors and device conductance matrix in hardware. b, Prewitt kernels for different convolution image processing. The symbol of each matrix element mapped from the conductance difference of HRS and LRS. c, The original input image. d-k, Hardware- and software-processed images with different kernels, including vertical, horizontal and soft edges. The combinations of vertical and horizontal edges are shown in f and j.
