Method for recognizing a pattern in an image and associated devices

The invention concerns a method for recognizing a pattern in an image comprising : - a training phase of an oscillatory neuron network, the oscillatory neuron network being adapted to output a pattern when an image is inputted, the oscillatory neuron network being implemented by a circuitry comprising oscillators (50) linked by interconnections (64) comprising at least one coupling resistance (66) having a coupling resistance value, the oscillators (50) being coupled by a sub-harmonic injection technique and coding the output by their relative phase difference, the coupling resistance values being learnt during the training phase by using Hebbian learning rules, and - an operating phase wherein the trained oscillatory neuron network is used to recognize a pattern in an image, at least one of the training phase and the operating phase being computer-implemented.
