From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Dear @linux and @academicchatter folks:

Please suggest libre/open source tools that allow for the extraction of text and images from scientific pdf documents?

P.S: I'm on a linux machine. Would like something terminal friendly, if possible!

The first tool I can think of is LibreOffice Draw

Maybe there are other tools, but I think LibreOffice Draw do the job pretty well

Edit: If the PDF has written text, you may wanna use an OCR tool, but I don't have any to suggest

@[email protected] OCRmyPDF is exactly what you are looking for

Try Zotero. It is a complete literature databas but it's PDF reader is very good at extracting images and text. Works on all OS, web and mobile. Native Linux client has been very smooth for me. Oh, terminal it doesn't do though. If you want to extract a large amount in an automated way, its probably not the right tool.

gImageReader is a graphical front-end to the open-source OCR program Tesseract, so that might be just what you're looking for. The default settings don't add the OCR'd text to the PDF but you can do that.

I'm mystified that poppler-utils is not a viable option. Of course the *.pdf file would have to include the text itself, but many do.
