1. An apparatus configured for object recognition, the apparatus comprising:

  • a receiver configured to receive a first visual signal representative of an object;

    an encoder configured to encode the first visual signal into a plurality of pulses; and

    a one or more detectors coupled by a plurality of transmission channels to the encoder;

    wherein;

    information related to identity of the object is encoded into a pattern of latencies of the plurality of pulses relative to one another;

    a parameter associated with the object is encoded into a group delay that is common to all pulses within the plurality of pulses;

    each of the plurality of transmission channels is associated with a delay configured to effect a coincident arrival of at least two of the plurality of pulses to at least one of the one or more detectors;

    the coincident arrival is substantially invariant to a change in a value of the parameter; and

    at least a portion of the plurality of transmission channels is configurable to be adjusted based at least in part on a second input signal, the second input signal temporally preceding the first visual signal.
