NORMALIZER FOR OPTICAL CHARACTER RECOGNITION SYSTEM |
摘要 |
<p>Signals produced by optically scanning different sizes and fonts of characters are normalized into a single format of data as an input to a character recognition unit. The signals are obtained by optically scanning characters with a single columnar retina and are used to produce a train of digital signals. Data derived from characters which are larger in size than a selected nominal are normalized by electronically weighting output signals from various photocells in the columnar array, summing the weighted signals and then averaging. The normalized output is delivered to a recognition unit to identify each character.</p> |
