optical character recognition (OCR) -> οπτική αναγνώριση χαρακτήρων

Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic translation of images of handwritten, typewritten or printed text (usually captured by a scanner) into machine-editable text.

OCR is a field of research in pattern recognition, artificial intelligence and machine vision. Though academic research in the field continues, the focus on OCR has shifted to implementation of proven techniques. Optical character recognition (using optical techniques such as mirrors and lenses) and digital character recognition (using scanners and computer algorithms) were originally considered separate fields. Because very few applications survive that use true optical techniques, the OCR term has now been broadened to include digital image processing as well.

OCR: Optical Character Recognition (Οπτική Αναγνώριση Χαρακτήρων). Πρόκειται για τεχνολογία που έχει αναπτυχθεί τα τελευταία χρόνια και επιτρέπει την "ανάγνωση" τυπωμένου ή χειρόγραφου κειμένου από ηλεκτρονικό υπολογιστή με τη χρήση σαρωτή (scanner) και την κατευθείαν μεταφορά του σ' έναν επεξεργαστή κειμένου, αντικαθιστώντας έτσι τη χρονοβόρα διαδικασία της αντιγραφής με πληκτρολόγηση.
