Abstract

Abstract Translated from German Eine beliebige auf Textinhalte hin zu untersuchende Druckvorlage wird optoelektronisch durch ein Videosystem abgetastet; die gewonnenen Abtastwerte werden digitalisiert zeilenweise verarbeitet; mittels mehrerer Verfahrensschritte werden bei Vorliegen von Text für die Textzeilen isolierte, d. h. einander nicht berührende, Schwarzblöcke gebildet, deren Anfangs- und Endkoordinaten mit denen der Textzeilen übereinstimmen und listenmäßig erfaßt werden. Any print template to be examined for text content is optoelectronically scanned by a video system; the sampled values are digitized and processed line by line; by means of several process steps, if there is text for the lines of text isolated, i. H. not touching, black blocks are formed, the start and end coordinates of which match those of the text lines and are recorded in lists.
