    Project mention: [P] Training to read PDF documents. Any ideas? | | 2022-05-20

    If all you need to do is OCR, check out , it's a similar architecture to the cloud services, without all the $. You'll end up with extracted text and bounding boxes for it.

    Project mention: PDF query? | | 2022-06-10

    Worst case scenario, if you're not able to convert the Spl directly to a searchable PDF you can OCR them after the fact with

  • unilm

    Project mention: Looking for help with inference using TrOCR from MS | | 2022-06-22

    I'm trying to use TrOCR, an OCR Transformer model from Microsoft. The model is available on Huggingface and I'm trying to use it in a colab notebook. My problem is that I cannot find how to do inference on a whole page using that model. All the examples seem to provide word snippets or line snippets for this, which is of course useless for real world scenarios. The engine itself can handle a whole image as an argument but the OCR results are garbage. My tests show the smaller the image the better the results and this seems to be confirmed by MS and their model description where it says that it was trained by breaking down an image into 16x16 segments. Can anyone understand how to do inference for a 2500x3300 A4 type image? A colab example would be great as well!

  • Paperless-ng

    A supercharged version of paperless: scan, index and archive all your physical documents

    Project mention: Document management system wanted | | 2022-06-23

    Apart from Paperless-NG and Papermerge there's also Docspell, Lodestone, LogicalDOC, Mayan, Teedy and probably more but I don't think that any of them might keep the structure.

  • pytesseract

    A Python wrapper for Google Tesseract

    Project mention: Extract Highlighted Text from a Book using Python | | 2022-02-22

    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.

  • tesserocr

    A Python wrapper for the tesseract-ocr API

    Project mention: [Question] I am trying to segment the image using python. | | 2021-08-09

    If you’re using tesserocr then you can use OpenCV images directly, so you can just extract the relevant image rows (e.g. query_image = main_image[prev_line:this_line]) and process then without needing to save each image.

  • LaTeX-OCR

    pix2tex: Using a ViT to convert images of equations into LaTeX code.

    Project mention: Need some help with installing LaTeX-OCR | | 2022-05-30

    Recently I found out this LaTex-OCR, which can convert images of math formula and symbols to LaTeX code, and it is based on Python. I looked at the instruction on GitHub and even found this video but I still got no idea about things like Pytorch that I need to install and how am I supposed to run those commands. Can someone help me with a detailed, step-by-step guide and some errors I might encounter (because I saw a lot of people having difficulties installing these)? I don't know anything about Python so hope someone can help me out:)) This will boost my work by a lot.

    A packaged and flexible version of the CRAFT text detector and Keras CRNN recognition model.

    Project mention: Why do new architectures still use old models? | | 2022-06-05

    Yes, you should be able to do it by replacing the the backbone and training the other parts again. The results may be better or worse than you expected. See:

  • receipt-parser-legacy

  • PaddleOCR2Pytorch

    PaddleOCR inference in PyTorch. Converted from [PaddleOCR](

    Project mention: [Technical Article] OCR Upgrade | | 2022-06-12

    Path №2: use the tools provided by the project to convert the models of the Paddle Inference to the PTH files of Pytorch, then use the tools in Pytorch to convert the PTH files to the TorchScript files in Trace mode, and finally use PNNX in the NCNN toolbox to output them to PNNX and NCNN formats, and take the model files in NCNN format for deployment.
