Understanding OCR Technology Fundamentals
Modern OCR systems have come a long way from their early days. Now, they use advanced imaging and software to turn static documents into searchable data.
How Optical Character Recognition Works
The OCR process starts with capturing document images. This is done by scanners or cameras. The quality of these images affects the next steps.
Then, image quality is improved. De-skewing fixes alignment, despeckling removes noise, and binarization makes images black and white. This makes characters clearer.
