What algorithm does OCR use?

OCR algorithms powered by neural networks (NN) use a different logic where the first NN layers aggregate pixels from the input file to create a low-level feature map of the image.

How does OCR process work?

A simple OCR engine works by storing many different font and text image patterns as templates. The OCR software uses pattern-matching algorithms to compare text images, character by character, to its internal database. If the system matches the text word by word, it is called optical word recognition.

Is OCR a machine learning algorithm?

OCR is a Machine Learning and Computer Vision Task

Modern machine learning algorithms make the text recognition process more advanced and provide a higher level of recognition accuracy for most fonts, regardless of input data formats.

What is the best OCR algorithm?

Popular answers (1) The tesseract algorithm is available on Google Code, and is one of the best open source OCR out there. I have attached the link. Join ResearchGate to ask questions, get input, and advance your work.
