Optical Character Recognition (OCR)

Optical character recognition (OCR) is sometimes referred to as text recognition. An OCR program extracts and repurposes data from scanned documents, camera images and image-only pdfs. OCR software singles out letters on the image, puts them into words and then puts the words into sentences, thus enabling access to and editing of the original content. It also eliminates the need for manual data entry. Watch IBM Master Inventor, Martin Keen, explain OCR's evolution and how OCR works today.

The OCR software GrabText
that I’ve been using recently is excellent. Not only does it provide accurate recognition, but its standout feature is the ability to recognize mathematical and physical formulas as well.

Very common in payment systems. The checks people use to send in to pay their bills used cameras, computers, and equipment to capture and process payments. The equipment's cameras would capture the OCR line at the bottom of the check (routing transit number/customer's account number). It's a font based system. After capturing this information, the OCR software would recognize the fonts of the OCR line and put this into a file so the banks could debit the accounts of their customers. Also, more currently, companies who use warehouse automation for material handling, use cameras for pattern recognition or better yet, bar codes for processing materials being sorted for shipping. The cameras and software used to capture the bar codes labeled on the material being put through robotic machines for sorting use deep learning to reduce read errors. The cameras have to be trained to recognize certain barcode structures. Once learned, they have an amazing capture rate for sorting materials. These are real examples of how deep learning and OCR are used in business today.

I'm calling baloney on Comic Sans—I *think* that was a joke, but that font happens to be particularly easy on many dyslexics. (This likely expands to Sans fonts in general, but i have no proof of that.) I think we can stop picking on it.

Amazing video. I'm interested in this technology. Are there any online courses for beginners that I can take, and in order to learn more about TTS, OCS, AI, and how it can work in different applications?

What an awesome video! Thank you! Could you point to a video the explains the high level architecture of an OCR model ie from training to prediction?

OCR with AI, I am using Keras for detecting text but it still fails to detect symbols like %, $ etc.

thank you for introducing me to comic sans

[dadoll]

can you consider OCR as a sample of Hyper Automation?

The "self-driving" Tesla Roadster currently near Venus never complained about Comic Sans ;)

I'm so sorry, but i have an important question that's rather irrelevant to this lecture, but hey, is there a window glass in front of him on which he writes? If yes, how does he mange to write each letter correctly?? I mean it is only a transparent window, right? Help 😮
