I hope this message finds you well. I am currently using ChatGPTo4 and have encountered an issue when trying to use Optical Character Recognition (OCR) for extracting text from images containing Japanese characters.
Previously, I was able to successfully extract text from Japanese images using the OCR feature. However, in the current environment, it seems that the Japanese language model is no longer available or supported for OCR, which is crucial for my usage. I receive an error indicating that the Japanese language is not loaded or supported in the current setup.
As I am a paying subscriber to ChatGPT and rely on the OCR functionality, particularly for Japanese text, I would appreciate any guidance or assistance you can provide. I would like to know if there is a way to enable or access the Japanese language model for OCR in my current environment, or if there are any future plans to support this feature.
Thank you for your time and support. I look forward to your response.
Successful, indicating that the current environment supports basic OCR for English text.
Root Cause for Japanese OCR Issues:
The problem seems specific to Japanese language OCR (lang="jpn"), which may point to one of the following:
Missing Language Data: The Japanese language pack might not be installed in the Tesseract setup.
Font Rendering Issues: Japanese text might have been hard to recognize due to font rendering or image quality.
Next Steps:
Install Japanese Language Pack: Ensure that the Japanese language data for Tesseract (jpn.traineddata) is available.
(ChatGPT platform is currently near-nonfunctional, not completing responses and even loading slow in general. With OCR attempts without specifying language parameter, the text was garbled nonsense).
There is OCR functionality available in the current environment, but there is a limitation regarding the Japanese language. The current environment supports OCR for languages such as English, but the Japanese language (lang=“jpn”) is not supported due to the missing language data.
OCR in English- Successful extraction using pytesseract, confirming that the environment supports basic OCR for English text.
*Japanese OCR Issues- The Japanese language pack might not be installed in the Tesseract setup, causing the extraction to fail.
You’ve received an uploaded Japanese language data file (jpn.traineddata) for pyTesseract and image files from a user. Perform OCR on the images using the following steps in your Python notebook environment to enable Japanese:
Set the TESSDATA_PREFIX environment variable to the mount point path containing the uploaded jpn.traineddata file to ensure Tesseract recognizes the custom language data.
Use the pytesseract library to perform OCR on the uploaded image, specifying ‘jpn’ as the language parameter.
Return the extracted text from the image.
Use your own computer vision to extract text to see if you have understanding. Synthesize your results with that of tessaract python to make a high quality image transcription.
Upgrade to native Japanese OCR software when the results are still poor.
