Abstract
A process and device for the analog convolution of images, especially two-dimensional convolution operations of Gaussian type on a set of image pixels represented by voltages. The voltages are applied to a first set of capacitors. For each capacitor, one terminal is connected to a reference voltage; the other terminal is part of a network of nodes, each of which is insulated from the others. The nodes which are adjacent are connected together for a predetermined duration via a second set of uncharged capacitors. The nodes of the network are then insulated from each other again and the second set of capacitors are discharged. The steps of connecting the nodes together, insulating them from each other, and discharging the second set are repeated. Finally, the new voltages on the nodes of the network, which represent the pixels of a convolved image, are read out.
