The abbreviation OCR stands for Optical Character Recognition. OCR is used to automatically recognize scanned text and text within images. The recognition rate essentially depends on the quality of the original. OCR is used for automated paper processing. OCR software can be used to scan, recognize and capture documents. Another focus is OCR invoice recognition.
While OCR involves the recognition of machine-generated texts, OMR (Optical Mark Recognition) is used for the automatic recognition of optical marks. This is often the case in the evaluation of forms, questionnaires or exams, when checkboxes or multiple-choice questions are to be evaluated. OCR software can be used, for example, to recognize relevant features such as postal codes, contract numbers or invoice numbers, and thus to classify the document in a workflow management system.
