Optical character recognition (OCR) is the mechanical or electronic conversion of images of typed, handwritten, or printed text into machine-encoded text. OCR technology has advanced significantly in recent years, enabling accurate and reliable text extraction from a wide range of sources including scanned documents, images, PDF files, and camera-captured images. OCR systems use techniques such as pattern recognition, feature extraction, and machine learning algorithms to analyze and interpret text characters from input images. OCR technology is used in various industries and applications including document management, data entry, content extraction, text-to-speech conversion, and language translation. It has revolutionized the way businesses digitize and process information, improving efficiency, accuracy, and accessibility. OCR technology is integrated into software applications, devices, and services to enable automatic text recognition and data extraction, reducing manual effort and increasing productivity.
