Apparatus and methods for temporally proximate object recognition

摘要

Object recognition apparatus and methods useful for extracting information from an input signal. In one embodiment, the input signal is representative of an element of an image, and the extracted information is encoded into patterns of pulses. The patterns of pulses are directed via transmission channels to a plurality of detector nodes configured to generate an output pulse upon detecting an object of interest. Upon detecting a particular object, a given detector node elevates its sensitivity to that particular object when processing subsequent inputs. In one implementation, one or more of the detector nodes are also configured to prevent adjacent detector nodes from generating detection signals in response to the same object representation. The object recognition apparatus modulates properties of the transmission channels by promoting contributions from channels carrying information used in object recognition.

1. Apparatus configured for object recognition, the apparatus comprising:
a receiving module configured to receive a first plurality of frames relating to an object undergoing a transformation; an encoder configured to encode at least a portion of a frame within the first plurality of frames into a group of pulses; and at least one detector in communication with the encoder and configured to receive the group of pulses, and to generate a first signal based at least in part on the group of pulses; wherein:
at least a subset of the first plurality of frames comprises a plurality of views of the object undergoing the transformation;the apparatus is configured to recognize the object in a view of the plurality of views invariantly with respect to the transformation;the at least one detector is adjustable from a first regime to a second regime responsive to a second signal;the second signal comprises a detection signal generated in response to a first frame of the first plurality of frames; andthe first regime comprises a first excitability parameter of the at least one detector and the second regime comprises a second excitability parameter of the at least one detector, the second excitability parameter being different than the first excitability parameter at least until a second frame of the first plurality of frames is received, the second frame being generated subsequent to the first frame of the first plurality of frames.
