1. A sensory input processing apparatus, comprising: a receiver configured to receive an input data frame comprising a feature; a sampler operably coupled to the receiver and configured to generate a sequence of sub-frames comprising a first sub-frame and a second sub-frame, at least one of the first sub-frame and the second sub-frame comprising at least a portion of the feature; an encoder operably coupled to the sampler and configured to receive and encode the first sub-frame and the second sub-frame into a group of pulses; and a first decoder coupled by a plurality of transmission channels to the encoder and configured to receive said group of pulses and to generate a detection signal; wherein: a displacement of the second sub-frame relative to the first sub-frame is configured to effect detection of the feature; and at least a portion of the plurality of transmission channels is configurable to be adjusted from a first scheme to a second scheme based at least in part on the detection signal.
