OCR - Image Reader

A powerful optical character recognition (OCR) extension to capture and convert images to text
What is OCR - Image Reader?
'OCR - Image Reader' is a Chrome extension that adds a toolbar button to perform OCR. Upon pressing, the user can select a region in the active window for the extension to capture. It recognizes text within the selected region using the powerful Tesseract OCR engine, supporting over 100 languages, auto text orientation, and script detection. This extension operates offline, only requiring an initial fetch of the language training database from the internet. It can extract text from images, pdfs, ppt slides, or web content when user-selection is prohibited. If extraction confidence is low, image inversion and retrying is possible, improving performance on dark themes.

Extension summary

This extension adds a toolbar button to your browser to perform OCR. When this action button is pressed, it allows the user to select a region in the currently active window. The extension captures the area and tries to recognize text inside this region using the internal powerful OCR engine (Tesseract engine). This extension uses the "tesseract.js" library that supports more than 100 languages, automatic text orientation, and script detection.

This extension loads the JS library on the page and removes it when you are done. This way, there is no long-term resource usage.

Notes:

  1. On the first run, the extension might take a few minutes to fetch the training data from the internet. Since this resource is cached, all subsequent calls are going to be fast.
  2. Optical character recognition (OCR) is slow, so this extension displays a progress bar for each detection module.
  3. This extension does the OCR process offline. There is no server-side interaction. It only fetches the language training database once.
  4. This tool can be used to extract the text content out of images, PDF documents, Powerpoint slides, or extract the content of a web page when user-section is forbidden.
  5. If the text extraction confidence is low, the extension inverts the image and retries (particularly useful on the dark theme)
  6. If the text extraction is not accurate, you can modify the image and drop it into the interface to retry.

Change Logs: Version 0.2.4: Supports browser-level page zooming and OS-level screen zooming Adds image language detection (still beta) (slow operation)
