Pixel hashing image recognition system

DETAILED DESCRIPTION It is an object of the present invention to provide a recognition system which directly correlates a received pixel pattern with a specific character or geometric shape.
It is another object of the present invention to provide a system of the foregoing type which employs a pixel pattern as a memory address, thereby enabling the use of hash based retrieval routines for recognition purposes, i.
e.
"pixel hashing".
It is another object of the present invention to provide for a system of the foregoing type wherein scanned signals corresponding to individual pixels are configured in a pixel array which is thereafter divided into a series of sub-arrays, each of whose pixel patterns directly corresponds to a unique address in respective memory portions (i.
e.
, sub-memories).
It is an object of the present invention to provide a system of the foregoing type wherein the address from each pixel sub-array interrogates its respective memory to provide a set of possible characters or geometric shapes which, when the sets are combined, indicate a single character or geometric shape as a solution.
It is a further object of the present invention to provide a system of the foregoing type which processes signals indicative of a single overall target pattern previously imaged at select distances from a reference to provide signals indicative of the target's present distance.
Still another object of the present invention is to provide a system of the foregoing type which processes images of an object at select rotational or translational positions as compared to an origin to provide signals indicative of the object's present position and orientation.
According to the present invention, a system for pattern recognition includes an apparatus for receiving a sequence of signals configured in a signal array, including signals denoting an overall pattern.
There is an apparatus for configuring the signal sequence into a plurality of signal sub-arrays, with each of the signal sub-arrays having a digital pattern corresponding to a portion of the overall pattern
