OCR, or Optical Character Recognition, is a technology that converts different types of printed or handwritten text into machine-readable data. It involves scanning physical documents or images containing text and using advanced algorithms to recognize and extract characters from the image.


The OCR process includes several essential steps. First, the input document undergoes preprocessing, where the image is enhanced to improve contrast, remove noise, and correct distortions for better recognition accuracy. Next, character segmentation identifies individual characters by dividing the text into segments, enabling the OCR system to recognize letters, numbers, and symbols accurately.


After segmentation, the recognition phase begins, where characters are identified and matched to their digital representations. This process utilizes pattern recognition algorithms, machine learning, and statistical models to map the extracted character shapes to known characters in its database. Finally, post-processing refines the recognized text, correcting errors, analyzing context, and ensuring coherence.


OCR offers numerous benefits across various industries. One of its primary advantages is in document digitization and archiving. By converting paper documents into searchable and editable digital formats, OCR facilitates easy retrieval and storage, streamlining document management and saving physical space.


The technology also enhances data entry processes, saving time and reducing errors. Instead of manual data entry, which is time-consuming and prone to mistakes, Optical Character Recognition automates the process, making it faster and more accurate. This is particularly valuable in industries dealing with large volumes of data, such as finance, healthcare, and logistics.
