OCR Anyone?
-
Working on an app that is very much table driven. I have "table data"; but not in text form; only images. Windows 10 has OCR! Using a PDF reader (and a nice zoom), I use the "Snipping Tool" to snip my "table", and save it as an image file. Then using the C# sample OCR app, I load the image and it extracts the text. I'm getting 95 to 100% recognition. The app highlights what it extracted from the image so you can see what "noise" was the issue (you could then pixel adjust the image, for example). Since it's possible to access clip board images, you could eliminate the file step altogether. Brilliant stuff, IMO.

I did not know Win10 had OCR out of the box for free. I used to use LEADTools OCR a couple of year's ago but that is mega expensive. Interesting.

Yep, for $3,000 (LeadTools) you could purchase a "whole lotta" Windows licenses, depending on your source and version and student status.

I am missing something. If that requires a C# sample app how is it that W10 has OCR? If it requires an external app then W10 does NOT have OCR at all. The app provides OCR.

I thought it was an app showing you how to use Windows 10 OCR assemblies. Perhaps I am missing something. Shows how to use the OCR API:
Windows.Media.Ocr

I'm planning to use Azure Cognitive Services for a small project for some OCR. More specifically, I'd like to automatically read dates, descriptions and prices on invoices when I upload them to my system. It's probably a hell of a lot of work and will save me little time, but I just wouldn't feel like a developer if I'd let this chance slip to automate in two weeks what I can do in three minutes :D

I must admit that I've never tested it but Windows has had automatic OCRing of TIFF files (if you install the TIFF IFilter) for at least a decade. As I say, I've never tested it but it was (and still is) there.

I wouldn't post a turd party crap and claim "Windows 10 has OCR". That would be spam, IMO. It's a "native" UWP app from the SDK "master" collection of "samples". (examples?) I included the link so people could "examine" the code and decide if it was useful (since it is quite "small"), and runs "out of the box".

From what I could tell, OCR, up to now, was for masochists. Just query OCR.

It can be hard to get an exact like for like OCR but it can often work well enough. I just tested the TIFF IFilter OCR ability and it seems to actually work (mostly). I took a screen shot of this forum page and saved it as a .tiff. I then used Windows Search to search for text within the file. I tried "must admit that I've never tested it" and it found it! (I admit that I had a lot of hits on the phrase so I added "kind:picture" to narrow it down to picture files so as to not have to scroll through pages of hits). I tried various words in the screenshot and one word that the TIFF IFilter failed to OCR was "masochists". Don't ask me why. ;-) I'll upload the TIFF somewhere if you want it but you can trivially create your own to test it with. You'll need to manually install the TIFF IFilter if you haven't already done so. ** edit ** I tested with some more search strings. When I accidentally searched for "makr them use EDI" (quotes included) it found nothing. When I corrected the spelling to "make them use EDI" (quotes included again) it instantly found it. Windows Search really is searching the OCR'd and indexed contents of the image file.

Make them use EDI.

That's completely not my use case, nor possible, nor wishful.

It does and you can even use the OCR API in a WPF or WinForms application: [OCR in WPF using the WinRT OCR API](https://www.codeproject.com/Articles/5276805/OCR-in-WPF-using-the-WinRT-OCR-API)
