1. An intelligent sensor system, comprising:
a sensor array, including:
a plurality of artificial intelligence pixels, each artificial intelligence pixel in the plurality of artificial intelligence pixels including:
a plurality of sub-pixel elements, each sub-pixel element in the plurality of sub-pixel elements including:
a photodetector; and
a neuromorphic element;
an artificial intelligence pixel summing node, wherein a weighted output from each sub-pixel element in the plurality of sub-pixel elements is provided to the artificial intelligence pixel summing node; and
an artificial intelligence pixel comparator, wherein the artificial intelligence pixel comparator operates to compare a summed output of the sub-pixel elements provided to the artificial intelligence pixel summing node to a first reference value established for the artificial intelligence pixel comparator, and wherein the artificial intelligence pixel comparator further operates to provide an output in response to a first comparison result; and
a plurality of summation and data reduction blocks, wherein each summation and data reduction block includes:
a summation and data reduction block summing node, wherein an output from at least some of the artificial intelligence pixels is received at the summation and data reduction block summing node; and
a summation and data reduction block comparator, wherein the summation and data reduction block comparator operates to compare a summed output of the at least some of the artificial intelligence pixels to a second reference value established for the summation and data block comparator, and wherein the summation and data reduction block comparator further operates to provide an output in response to a second comparison result.
