Method for finding and delimiting letters and letter groups or words in text areas of an original which can also contain graphical and/or image areas apart from text areas

摘要

An arbitrary printed original to be examined for text contents is optoelectronically scanned by a video system; the samples obtained are processed digitised line by line; when text is present, the extreme coordinates of objects in the form of letters, letter groups or words isolated in text lines and other information parts relating to these objects are determined and registered in lists by means of a number of method steps.
