PDF to Text OCR Converter Command Line

What is OCR technology?

What is OCR technology? OCR is short for optical character recognition. It’s a technology which enables you to change any scanned images of handwritten, typewritten or printed text into machine-encoded text. OCR is now used in many enterprises, not just libraries and government. (Note: OCR technology is not new, because it has been developed since 1912). Now, OCR technology can reach 98% accuracy. But OCR technology will decrease the accuracy when processing the images with different quality. And for OCR technology software, the quality of images is really important. Basically, OCR technology software requires a 200 megapixel camera with auto focus at least.
