I'm an independent consultant in the documents space.
Do you need to extract text from PDF documents (unstructured, semi-structured or forms)?
Do you have an OCR problem?
I can probably help.
Feel free to contact me: ocrcustomserver@gmail.com
What is the reason that you want to roll your own? Is it because you want to own the IP or for learning purposes?
For the state of the art check the ICDAR, DAS and ICFHR (for handwriting) conferences. For an overview: https://github.com/handong1587/handong1587.github.io/blob/ma...
What is the accuracy that you're getting from it?
From the Tesseract FAQ: "Can I use Tesseract for handwriting recognition? You can, but it won’t work very well, as Tesseract is designed for printed text. Look for projects focused on handwriting recognition."…
(literally just scale it up x2 or x4). Just to clarify, the input image should be 300dpi.
In this case, the use is extracting words that can be used in full-text search, so structural extraction isn't a key criteria. In case someone wants to know more, the former is known as "full page OCR" and the latter as…
Typically OCR accuracy is measured in two ways, CER (Character error rate) and WER (Word error rate). If just one number is provided, it's typically CER. "Finding words in images" is a bit ambiguous. It can mean "word…
"The problem is that while Textract works really well for well defined tabular data it does not work for tables where the rows and columns are implied with white space, instead of lines." This is what Tabula and Camelot…
Accuracy of Google OCR vs Tesseract v4 (on books and web): https://imgur.com/a/Tj0TASf
The Apple Newton was capable of online OCR (doesn't have to do with internet connectivity in this case). As you mention, online OCR is when you input the strokes directly on the device vs offline OCR where the input is…
I'm curious, if you email me a sample I can tell you what's possible.
The reason is that online OCR (this particular case) is entirely different from offline OCR. Online OCR is when you input the strokes directly on the tablet/phone, so it becomes a sequence of XY coordinates with an…

Does a list of all hospitals (in each state) exist somewhere?
pdfminer is another good library (Python).
If this is important to you (extraction of information like ID/name/date from non-searchable PDFs), you could send me an email and we could discuss it further. I might be able to help you with this.

There's ABBYY FineReader Engine CLI for Linux: https://www.ocr4linux.com/
This is very interesting. I'm curious to see how they will execute on several points: 1. How it will deal with multiple templates that the system hasn't seen before. Especially when there is significant difference…
As tracker1 mentioned, don't think of this as for reflowing text for different devices but as a data capture and documents processing solution. Example: You are dealing with a lot of PDF documents that contain…
Shameless plug: I work on custom solutions that do this locally, shoot me an email if interested.
There's Google Cloud Vision and Microsoft Cognitive Services that act as competitors to Amazon Rekognition, but AFAIK there's no offering from a FAANG that competes with AWS Textract. It looks like it's competing with…
The docs page [1] (subject to change) mentions: Do you support handwriting? – We do not support handwriting extraction. [1]: https://docs.aws.amazon.com/textract/latest/dg/how-it-works-...
OneNote can do transcription (copy text from image).
Yeah, Evernote's OCR engine will generate possible candidates for every given word and will sort them internally by confidence score. Screenshot: https://s24953.pcdn.co/blog/wp-content/uploads/2018/02/longh... Since…
