Using tesseract-ocr we can extract text from images. I have tested gocr which didn't work well as compare to tesseract-ocr. Installation: sudo apt-get install tesseract-ocr Python program to convert all the image files with png extension inside of current directory to txt file
So, given the age of the above mentioned posting, are there any better tools for extracting text from images or photographs? EDIT 1: With "image containing text" I mean, that I have a PNG/JPG/BMP file as a source and that I want to extract the pixelized text within it and have an ASCII/UTF-8 text as result and output.
Now run this command whenever you want to copy text from selected part of your screen... rm -f /tmp/a.png && flameshot gui --path /tmp/a.png && python3 /image2text.py I have created a custom shortcut (mapped to shift+prtsc) in my linux, so I just press shift+prtsc whenever I want to copy text from image file...
I can embed text and then extract it using steghide just fine. I have tried extracting the embedded information after slightly cropping the image, which results in: $ steghide extract -sf myImage.jpg -xf myImage.extract.txt Enter passphrase: steghide: could not extract any data with that passphrase!
Use the edit tool (Alt+1) to select the image you need to extract; Copy the figure (Ctrl+C) Click on the surrounding dashed frame around the image and check out the right sidebar (Object Inspector) and click on "Geomerty". There you can see the size of your selection; Create a new file (Ctrl+N). It will prompt you to provide the page size.
I want to process the body of text and extract an integer from a specific position in the text, but I'm not sure how to describe that 'particular position'. Regular expressions really confuse me. I spent (wasted) a couple hours reading tutorials and I feel no closer to an answer :(
Also, you could apply those tools after the color-to-alpha if the text had somehow got grey edges. Edit: Alternatively, you can use the select by color tool. This method kind of assumes you're using a black foreground on a white background, and wouldn't work for other colour combinations unless you change the last step.
You can clone from the image file to a drive. You can clone from the .img [image] file to a drive, for example a USB pendrive, that is big enough. This is the basic intention of the file. You can use mkusb for that purpose. It works with compressed image files too (when compressed with gzip and xz), .img.gz and .img.xz files.
epub2html is a simple command-line utility for extracting text from EPUB documents and, optionally, re-flowing it to fit a text display of a particular number of columns. It is written entirely in ANSI-standard C. Usage example: epub2txt input.epub > output.txt
So if you want to extract page 32 to 65 of sourcefile.pdf in a new file called extract.pdf, you can type these commands : mkdir tmppdfdir pdfseparate -f 32 -l 65 sourcefile.pdf tmppdfdir/page-%d.pdf pdfunite tmppdfdir/page*.pdf extract.pdf rm -rf tmppdfdir/ Warning : Be sure that tmppdfdir do not already exists before !
