From Scan to Text: How the OCR Process Works
The OCR process is a detailed procedure that involves several steps to convert an image into editable text. Initially, a digital image of the text is created, either by scanning or photographing the document. This step is crucial as the quality of the image affects the accuracy of the subsequent steps. The next step is image preprocessing, where the image is cleaned and optimized, as described by Parseur.
Image enhancement includes various techniques such as denoising (removal of image noise), deskewing (correction of distortions), line removal (cleaning the image from unwanted lines), and script recognition (identification of the font used). These steps are necessary to create the best possible foundation for character recognition. The Berger Team emphasizes that preprocessing is essential to reduce noise and correct distortions.
After image preprocessing, the actual character recognition follows. Pattern recognition and feature extraction are used here to identify the characters in the image. Pattern recognition compares the characters with databases of known characters, while feature extraction analyzes specific features of characters to identify them. Finally, post-processing and error correction are performed, where language models are used to correct errors and the recognized text is converted into editable formats like Word, Excel, JSON, or HTML. Our editing services help ensure the quality of your documents.
OCR Technologies: From Simple to Intelligent
Optical Character Recognition has significantly evolved over the years, leading to various OCR technologies and classifications. A fundamental distinction is between simple OCR and intelligent OCR (ICR). Simple OCR is limited to printed, standardized fonts, while intelligent OCR (ICR) can also recognize handwritten text and various fonts. Adobe states that modern OCR systems use algorithms and AI, including KNNs, to enable handwriting recognition and process entire lines of text simultaneously.
Intelligent OCR (ICR) employs Machine Learning and neural networks to improve recognition accuracy. These advanced algorithms allow for the recognition of not just individual characters but also whole words and character patterns. Additionally, there is Optical Mark Recognition (OMR), specifically developed for detecting marks on forms and tests. This technology is frequently used in the automated evaluation of exams and surveys.
Modern IDP platforms combine OCR with AI technologies like NLP and ML for advanced document understanding and automation, as EXB emphasizes. This goes beyond simple text recognition, offering comprehensive solutions for document processing. At Mentoc, we utilize cutting-edge OCR technologies to deliver the best possible results to you.
