Method and apparatus for reducing data in a pattern recognition system
Abstract
Abstract A DATA REDUCTION METHOD IN PATTERN ANALYSIS IS DISCLOSED HEREIN IN THREE SEPARATE PHYSICAL EMBODIMENTS. THE METHOD IS TO INTERLEAVE DATA REDUCING MEASUREMENTS. ADJACENT MEASUREMENTS ARE NONOVERLAPPING AND ARE INTERLEAVED SO THAT THEY ARE NOT IN HORIZONTAL OR VERTICAL ALIGNMENT. SINCE THE MEASUREMENTS ARE NOT SO ALIGNED, THEY PRODUCE A MORE ACCURATE REDUCTION OF DATA. IN OTHER WORDS, THE POSITION OF THE PATTERN UNDER THE DATA REDUCING MEASUREMENTS HAS LITTLE EFFECT ON THE REDUCED DATA. THE INTERLEAVING MAY BE ACCOMPLISHED USING ANY TYPE OF SCANNER SUCH AS CATHODE RAY TUBE, LINEAR ARRAY OF PHOTOSENSITIVE DEVICES OR RETINA ARRAY OF PHOTOSENSITIVE DEVICES. VIDEO DATA FROM THESE SCANNERS CAN BE EITHER TEMPORARILY STORED AND THEN SELECTED TO FORM THE DATA REDUCING MEASUREMENTS, OR AS IN THE RETINA SCANNER THE DATA CAN BE DIRECTLY REDUCED BY MEASUREMENTS OPERATING OFF OF THE RETINA.
