Please guide me about how to proceed with the OCR Plugin idea,

read this topic and read the updated GSoC 2024 live blog

In the proposed idea mentioned in the ideas-2024.md, was it proposed in Node.js or javascript? Here they have performed OCR using python. And that's complicated for an average person to achieve. This is achievable in JS.

OCR for existing Joplin Notes: Feb '21

Shall I start with proposing this idea in the features section?

Oh yeah. Missed that, apologies. Thanks for taking your time

Here are some parts of the Joplin codebase that might be helpful to look at:

joplin/packages/lib/services/ocr at dev · laurent22/joplin · GitHub
The lines in NoteEditor.tsx responsible for showing resource search results.

Silly question... I've updated my joplin to 2.14.x and activated OCR.
Does OCR now still only work for new notes?

laurent · 2024-03-05T13:59:36.281Z

No, it's going to process all your existing notes too

Isaac · 2024-03-05T14:36:23.100Z

perfect - can I see the progress in the log or elsewhere?
(I have about 3k notes with attachements)

laurent · 2024-03-05T15:30:29.834Z

Yes, if you open the console and filter on "ocr" joplinapp.org/debugging

Isaac · 2024-03-05T16:07:09.567Z

I'm getting this error in the log

laurent · 2024-03-05T16:50:43.869Z

Yes this is a known issue that was just fixed, and it will be in the next 2.14 patch release:

Is there a way to view what text was OCRed from an attachment? I have moved up to the latest 2.14.19 on Windows and several screenshots that I have put in a note are not being found by the text in them. Looking at the Console, I can copy/delete/paste the image back in and see that the OCR process finds it and says it processes with no errors.

I have downloaded tesseract and run the same image through it. It finds the text, including the text I was using for the search.

Also would like to know that

harun27 · 2024-03-23T12:56:06.680Z

Is there a possibility to search OCR only in one note? I tried filtering the notes with id:... but it didn't work. The easiest way would be if i could just do the normal ctrl-F search and it would search also through the images.
