Optical Character Recognition (OCR) is a technology that enables the recognition and extraction of text from scanned documents or images. It employs sophisticated algorithms to analyze the visual patterns of characters, transforming them into machine-readable text. OCR goes beyond simple text extraction and can retain formatting elements. It can also identify complex structures like tables, columns, and paragraphs. Thus it ensures that the converted text has the original document's layout and organization.

  • Preprocessing:The uploaded document undergoes preprocessing, including tasks like image enhancement, noise reduction, or rotation correction. These preprocessing steps aim to optimize the visual quality of the document and improve OCR accuracy.
  • Optical Character Recognition:The OCR engine analyzes the document, recognizing individual characters or words and converting them into machine-readable text.
  • Text Extraction:Once the OCR engine completes its analysis, the recognized text is extracted from the document. The extracted text is then available for further processing, editing, or downloading.
