Integrated device for recognition of moving objects
First Claim
1. An architecture for a single-chip object classifier comprising:
- a retina having an image plane upon which an image of an object to be classified is focussed, said retina organized as an array of rows and columns of pixels, each pixel containing a photosensor, outputs from said retina comprising a plurality of analog electrical signals derived from said photosensors providing a representation of said image;
position-recognizing means for identifying the portion of said image plane containing said image of said object on said retina;
object-recognizing means, responsive to said position-recognizing means, for examining a portion of output from said retina corresponding to the portion of said image plane containing said image and determining the similarity of said object to a plurality of learned classes of objects.

Abstract
A moving object classifier is integrated onto a single integrated circuit chip and includes a retina comprising a two-dimensional array of photosensors upon which the image of the object of interest is focused. A position classifier receives inputs from the retina and determines where in the retina the image of an object is located. An object classifier receives inputs from the portion of interest of the retina and computes the degree of membership of the image to each class to be classified and determines which class has the largest membership function. A scan controller controlled by the position classifier limits the object classifier data to the portion of the retinal image which contains the object. An interface controller interfaces the other elements on the integrated circuit chip with a microcontroller, which comprises a standard CPU, memory and input/output lines interfacing to the interface controller.
