Automatic pattern recognition method and apparatus particularly for optically recognizing characters

摘要: Apparatus for recognizing multi-font alphanumeric characters comprises a single line of detectors scanning the along plurality continuous scan lines each extending in direction height characters, and means sampling all time predetermined detector, located substantially midway lower-case excluding their ascenders descenders, senses change sign its sensed portion character. High low limit sensing linear array sense average tops bottoms projected control alignment to align between latter detectors, size-control vary size optically so that coincide with high detectors.
