ABSTRACT:
An analog parallel device for the local processing of a bidimensional signal comprises an input means, a processing means and an output means, the input means receiving the bidimensional signal and supplying, on a group of elementary input points organized in matrix-like manner, a group of parallel electrical input signals, the processing means receiving said input signals and supplying, on a group of elementary output points organized in matrix-like manner, a group of parallel electric output signals, each of which is obtained by a linear or non-linear combination of a plurality of input signals, the output means receiving said output signals, said means being realized in the form of thin films on a substrate.
This device may be particularly applied to local image processing.
