Richard3 1 Posted May 3, 2015 Share Posted May 3, 2015 I am premium member who primarily uses the Evernote desktop application on Windows 7. I have been using Evernote for over 2 years now and I have never been able to search for text in images. I am also unable to search for text in images in Evernote web (neither Chrome, nor Firefox), nor on Evernote mobile (Galaxy S4). I have done much searching online and as far as I'm aware, this feature ought to function by default. Is something wrong or is there a setting I need to change? Link to comment
Level 5* gazumped 12,021 Posted May 3, 2015 Level 5* Share Posted May 3, 2015 Hi. First my unhelpful comment: if you do your own OCR, you never have to worry about whether your document is the right size, resolution or type to get 'automatically' OCR'd. Now that's out of the way - what file type are you saving - JPG / PNG / PDF? And at what size and DPI resolution? Link to comment
Richard3 1 Posted May 3, 2015 Author Share Posted May 3, 2015 Perhaps I don't understand what OCR is. I though it was the technology that can read text from images as that is the feature I am hoping to have. Pretty much all my images are JPGs at 72 DPI since virtually all of them are from the web. I also have a few PDFs. The various resolutions range anywhere from 100 pixels to 2,000-ish. Link to comment
Level 5* gazumped 12,021 Posted May 4, 2015 Level 5* Share Posted May 4, 2015 Actually I was being more unhelpful than I knew at the time - my Adobe software doesn't OCR pictures most of the time*. I pre-OCR PDF files mainly because I then know it's done! There's an Evernote blog article about image OCR which may help you - the quick summary is that OCR will only process bitmaps (BMP images) in PDF files, and that the sharper the image the better... https://blog.evernote.com/tech/2013/07/18/how-evernotes-image-recognition-works/ * Edit - my PDFs are mainly text. Edit Edit: And I'm a cup of coffee short of coherence yet - images have to be synced a couple of times to be OCR'd - these previous threads may help! https://discussion.evernote.com/topic/24070-imported-jpeg-files-not-ocrd/ https://discussion.evernote.com/topic/65249-search-issue-issue-w-ocr-jpegs-worked-1st-day/ Link to comment
RobertJSawyer 167 Posted May 6, 2015 Share Posted May 6, 2015 Images take a little while to be OCRd by Evernote. You can't IMMEDIATELY scan an image and search for text in it, but you should be able to search for it a little while later (premium users get their images processed faster).NOTE: OCR is done on the server side after your notes have been synched to Evernote's cloud computers. If you have synching turned off, or are working with an offline (local-storage-only) notebook, OCR will not occur. The link below is a snapshot of a novel I wrote sitting on a bookstore shelf. Try uploading it into your Evernote account, make sure you've synched, and come back an hour or two later and search for the phrase "murder on the mean streets of mars". If Evernote DOESN'T turn up the note containing this image, you've got a problem; if it DOES, then OCR is working as intended.http://sfwriter.com/sawyer-evernote-ocr-test.jpg All best wishes.

Frank.dg 1,385 Posted May 7, 2015 Share Posted May 7, 2015 Make sure you're doing a global search and not searching within a note itself - i.e. Ctrl+F will not work on web and desktop for searching text within images... and neither will searching within a note on mobile device. Always from the global search bar. If you're wanting to hone in on a single note to test whether OCR is working, you may want to filter for that note you know you have, say, using the <Intitle:"your note title here"> operator. Once you've singled out that note, you can try typing in any phrases you see within an image. Another thing I figured out way back is that if you edit the note containing your image in any way, including adding a tag, the attachments within the image will show as not indexed, even previously indexed images (under the information icon on desktop). The fix for this is to hit Ctrl+Help menu in the uppermost toolbar on Windows desktop > "Fix Current note". This will re-index attachments for that note on your local machine. I suspect what is happening with many people is that in fact, the images are being indexed and OCRed way quicker than they think... but as part of their workflow they may be tagging certain/ all notes, which would bump the notes' out of their indexed status. Here's a video clip to illustrate: BTW, this should not affect your searching on the web client or mobile devices, since they contact the Evernote servers directly. This seems to be a Windows-desktop-only quirk. Link to comment
