What software is the current leader in OCR solutions?
- saradhi 6y agoBe it handwritten or printed text, by far, Microsoft's Azure OCR is best in recognizing text.
- kccqzy 6y agoLook into various paid offerings on the cloud. Azure, GCP, AWS all have OCR-as-a-service they outperforms local software.
- DarthGhandi 6y agoFor anything long term and high volume it's far cheaper to use open source solutions and hire a manual review team in the developing world where English is a common second language. Unless you are comfortable with the high rate of errors there's still a need for review. For small one-off tasks the cloud solutions do fine.
- nl 6y agoAbbyy FineReader is generally better than any of the major cloud vendors in my testing. See also this previous discussion: https://news.ycombinator.com/item?id=20470439 https://news.ycombinator.com/item?id=20470439
- kayhi 6y agoThanks, I had looked that over but thought things may have changed in the last year.
- unityByFreedom 6y agoAlso quite expensive since it is at the head of the pack IIRC. There is probably some value in making a competitor with new deep learning techniques provided you have a sufficiently diverse training set. It would take years to build tho.
- nl 6y agoI've done some work on deep learning approaches - specifically table extraction. It's not at all obvious how to make this work - there is a lot of human judgement involved in judging what a header is vs what are values, especially with merged header column/row columns.
- unityByFreedom 6y agoYeah I remember Abbyy also has an interface to define layouts for this kind of problem. I.E., this thing is a table and here are the headers etc. Sorry, I was not trying to say deep learning would be a substitute for all such issues, just that new approaches may help a smaller team build those tools more efficiently. I don't know if Abbyy combines its layout tool with training a model for customers, but it seems like a reasonable thing to build and expose.
- gnicholas 6y agoFor one-offs, you can use SensusAccess. I've found their quality to be pretty good.
