This process involves several steps:

• Image Preprocessing:The input image is cleaned up to remove noise, enhance contrast, and improve character recognition accuracy.
• Character Segmentation:The image is divided into individual characters, separating them from each other and the surrounding background.
• Character Recognition:Each segmented character is compared against a database of known characters to identify its corresponding letter, number, or symbol.
• Text Formatting:The recognized characters are assembled into words, lines, and paragraphs, preserving the original document’s layout as much as possible.

OCR has revolutionized document processing, making it possible to easily search, edit, and reuse information from scanned documents, eliminating the need for manual retyping.
