ITK VS tesseract-ocr

Yeah, Prolog is pretty cool!

Another technology I found interesting too learn is ITK (https://itk.org/). You need a different mindset using ITK than other image processing libraries.

Lisp is cool as well.

And fully homomorphic encryption.

VTK is a powerful visualization package, but it's more for working with 3D FEM/CFD data. There are lots of things in there though, so it may be useful. The sister project Paraview is an application which can be used to work with data interactively. Both have great Python support. There is also ITK which is focused on with image data, like medical scans - never used it, though.

if your order forms are photos or faxes, you could use an ocr tool like tesseract (https://github.com/tesseract-ocr/tesseract) to convert the images to text so that you can then parse the text and import it into google sheets.

Then it uses tesseract to analyze each image, extracting the text.

Here is a little and unspectacular script to read text from screen. It uses tesseract to ocr the text and import command from ImageMagick to make a screenshot. Then the script outputs the recognized text to stdout. You could replace the screenshot tool with something else you like, but the script expects the created files.

The only open source OCR I know is Tesseract

Ran the first open source command line time for OCR that I could find, in this case https://github.com/tesseract-ocr/tesseract .. the command was pretty straight forward: tesseract -l eng book.tif out_from_tiff Again.. a simple shell script should be easy enough to write and apply it to all pages. The output did have a form feed character at the bottom.. Obviously you can manually delete it but that would take forever.. so simply run..

That being said, the tool is using a tesseract-related wrapper, and it might be having trouble picking up the text.

compiling Tesseract OCR or getting the binary https://github.com/tesseract-ocr/tesseract and downloading it locally to your project

I'm going to use the Tesseract OCR engine and library, and its Python wrapper PyTesseract for text extraction. But there are numerous libraries out there to extract text from an image. In a real world application I would probably use cloud services from AWS, Google or Microsoft to handle this task.

If this doesn’t fix it then check out this GitHub issue for more troubleshooting steps.

If you want an SDK for this you can use https://github.com/PaddlePaddle/PaddleOCR or https://github.com/tesseract-ocr/tesseract
