Candidate article recognition with assignation of reference points and respective relative weights
First Claim
1. Image recognition apparatus for recognizing a condition of a candidate article with respect to a reference condition, said apparatus comprising:
- first memory means for storing a bi-level reference image;
display means connected to said first memory means for displaying said reference image;
selecting means connected to said first memory means and said display means for manually designating a plurality of selected reference points of said reference image;
detecting means that has at least one adjustable parameter and is connected to said selecting means for detecting signal levels at each of said reference points;
second memory means connected to said detecting means for storing said detected signal levels; and
comparison means connected to said second memory means for making a comparison of said detected signal levels with bi-level signals at points that correspond to said reference points but are proper to a bi-level candidate image corresponding to a candidate article;
said comparison indicating a condition of said candidate article with respect to a corresponding condition of said reference image, and said display means displaying the results of said comparison;
wherein each of said points correspond to a plurality of picture elements and said detecting means comprises means for adjustably assigning relative weights to said picture elements.

Abstract
A high-speed image recognition system operates in response to a binary digitized picture image signal. The system comprises a first memory for storing a bi-level reference image pattern therein, a selector coupled to the first memory for manually designating a plurality of selected points of the bi-level reference image pattern, a detector coupled to the selector for detecting signal levels at each of the points selected by the selector, a second memory coupled to the detector for storing therein detected signal levels obtained from the detector, and a comparator coupled to the second memory for comparing the detected signal levels at the selected points of the bi-level reference image pattern with signal levels at the same points of a candidate image pattern, whereby an object corresponding to the candidate image pattern is recognized.
