I've been a subscriber to your channel for a couple of years and I like all of your videos, but this is my favorite kind of video -- about a *useful*, open source tool or utility, not specific to Arch linux, not about gaming, not about drama in the industry. I'm not saying the other kinds are bad or that you shouldn't make them, but I like this kind the best.

I have used tesseract a bit for digitizing recipes from recipe books. When it does not give good results on a first past I have found that altering the image can help a lot. Altering the image to black and white, altering the contrast, and even enlarging the image can all improve results.

So if Google is maintaining this project, is Google Lens just a front-end for Tesseract?

[dergeneralfluff]

I started using tesseract for a project to gather the text off my memes hosted on my personal szurubooru (In an attempt to be able to search for set text, so you are able to actually find stuff within the thousands of images).

It has been very hit or miss, sometimes it gets text right down to the punctuation, other times it gets nothing, on low res bad contrast images were I think it has no shot it gets it, on clean images it gets nothing. Sometimes doing crazy image manipulation helps, sometimes unmodified is best.
What I can say is that handwritten Latin letters are impossible for it, so manga scanlations text is just blank for it, at least with the English language setting

A little script can be done alongside a screenshot utility to get OCR from screenshots directly to the clipboard

[muctebanesiri]

you have video about every topic. that's awesome.

[atomixhawk]

I use a keybinding to invoke a script which takes the screenshot of an area, pipe it to tesseract and copy the resulting text contents to the clipboard.

i use tesseract in python to read text and train the machine. good job explaining this 👏

[khaibaromari]

the sad thing about pytesseract is it works as long as the background of your image is of semi-color, other than that it would mess up everything.

Thanks for the helpful video Brodie. Do you know if you can use Tesseract to convert a non-OCR'ed PDF into a PDF that contains OCR'ed text?

[damarh]

OH lol, something just hit me, Google lens uses their own Tesseract OCR for extracting text and send it to your PC where you are logged in with your google account.

This seems fairly nice for searching tango. Maybe you should also check if it can do well checking the words 1 by 1, perhaps with some other ways of framing them. I am curious how it works on Middle Eastern languages like arabic and hindi though.

Anyone, know how could I add a second language in the same command line? I tried the next command and it doesn't work: tesseract filename.jpeg - -l ara[+spa] filename.txt

[solidhyrax]

Are you able to input a URL instead of a local file on your PC? This would be very useful.

Excellent. I made the mistake of writing a couple thousand small notes in the stock Samsung notepad on my phone, and it turns out the garbage developers only allow you to bulk export them as PDFs instead of plain text. This will come in handy.

Any one know how to set xsane to use tesseract?

[mattaku]

Google can't just repeat that, google drive to google docs conversion beats tesseract

I'm a huge japan-fan, love the culture, the food and people... but anime/weebs? Cringe.

I found use --oem=1 helpful, it forces to use the new ml model which helps a lot of cases
