scan and read under Linux

scan and read under Linux

[Ryan Mann]

Hello.  I have the Fedora Mate spin installed on a computer. I have a 
USB Cannon scanner connected to the computer and I was able to scan a 
document using Document Scanner.  I was able to save the document as a 
PDF file.  How can somebody who is blind read a PDF using Orca? When I 
enter on the document, it opens up in Document Viewer, but I can't read 
the document using Orca.

Well Ryan, why not save as a plain text file-and-read in a console? Or you 
could send that pdf to robobraille to convert.

Press F7 in the document viewer, then click "Enable." This should allow
you to read the document. If not, you should be able to open the file in
either Firefox or Brave, possibly Chromium as well. If nothing else
works, as soon as the document is open, press control+a to select the
entire document, then press control+c to copy it to the clipboard, then
open pluma and press control+v to paste the text into the editor. One of
these methods always works for me to read a pdf file using Orca. Hope it
helps.

PDf does not mean that it is a "text document", could also have been
scanned as an image.

The pdf would need editing since it's missing a LANGUAGE attribute.
That's why it won't talk with a screen reader in use.

[-- Attachment #1: Type: TEXT/PLAIN, Size: 1215 bytes --]

This is quite correct.
based on the steps you outlined, an image seems likely.
If the Orca specific suggestions do not work, may i echo one Chime 
provided?
send the pdf file to robobraille.
convert@robobraille.org
attach the file, simply placing what you want the end product to be in the 
subject field.
html or rtf or txt for example.
Robobraille will send back the results, often quite swiftly.
Hope this helps,
Karen

Hello,
Linux Intelligent OCR solution - LIOS is the Linux equivalent of 
Finereader on Windows. You can use it to scan say a book with a scanner 
and have it recognized, I believe using an already existing PDF is also 
possible. It supports multiple OCr engines as backend, Tesseract is the 
default-one I believe.

Best regards

Rastislav

You need to run OCR on the PDF file if you haven't done so already. 
Otherwise, it's just a series of images of the scanned pages.

making YouTube (etc) videos more accessible?

[Rich Morin]

The discussion of scanning and converting PDFs reminded me of a topic I've thought about a number of times.  Perhaps some folks here will be interested...

I watch a lot of conference presentations on YouTube (etc).   Typically, these have been edited into a collage, showing the speaker, a display screen, and perhaps some graphics for the event.  The display screen generally shows styled text, bullet points, charts and other graphic images, etc.

Although a blind person can listen to the audio track, they will miss all of the visual content.  So, I've wondered what the prospects might be for improving this situation.  For example, it seems like it should be possible for software to:

- pull static images from the video stream
- recognize the region containing the display screen
- extract text and layout information
- convert this to HTML
- synchronize the HTML to the audio track

Or, in this age of LLMs and such, perhaps the software could analyze the visual content and be prepared to discuss it interactively.   Might anyone know of any work in this area and/or have thoughts about how such a facility "should" work?

You would have the screen reader jabbering over the presenter, so I'm not sure that would take off. Audio description is usually slotted between dialog in tv shows and movies, so I'm not sure this approach would work for the type of content you are talking about.

Re: making YouTube (etc) videos more accessible?

The screen reader (or whatever) wouldn't have to be "jabbering over the presenter".  For example, the user could pause the video to examine and/or discuss a given slide.  If desired, the user could be alerted each time a new slide comes up (eg, by a short tone).

One of the useful aspects of recorded presentations is the ability to pause and review sections which "went by too fast".  I frequently do this myself, pausing the video to examine a slide of interest.

Oh, recorded presentations. Yeah that's different. Your scheme could work, it sure would be interesting to try out. Especially with code camps.

Re: making YouTube (etc) videos more accessible?

[Jude DaShiell]

Perhaps more useful would be one message stating presentation visual
content available then the system grabs each piece and puts it in a slides
folder and maybe does ocr on each of the slides in the folder in the
background and saves the output to a texts folder.  A user then could
listen to the presentation then read the texts shortly after the
presentation.
