To figure out what's going on, let's consider the convolution kernel that implements a three-pixel-square box blur: When the computer apples this kernel to an image, it considers each pixel in the ...

Optical convolution kernel based on the volatile-modulation-compatible photonic memory: (a) Schematic architecture of a 4×4 OCK. The inset is the discrete device of OCK. (b) The nonvolatile multi ...
