Multi language OCR witgh Cloud Vision API

[Martin]

Greetings,

We want to build a tool for pasting/uploading images of texts (in this case they are in English with diacritics and Devanagari) and then having the user tag the language areas of the image and then sending each image portion to an API for recognition.

We've tested Google's OCR on individual images via the Google Drive tool to convert an image to a Google Doc and it seems quite good.

I was wondering if we could use this API to automate such a process?

If anyone has done this or would like to do this or knows more about this we would be most greatful.

Warmest Wishes,

Martin

Based on the Vision API docs, this seems possible. You would want to send over an image and specify you want to attempt OCR by setting the TEXT_DETECTION feature (per https://cloud.google.com/vision/reference/rest/v1/images/annotate#ImageContext). Unfortunately the examples I see on the site are in Python and I'm a JavaScript guy. This is something I'd like to explore for a project of my own, however, so I'll post again if I have some code to share.

Hi all,

Ram: thanks, would be good to see some Node.js love :)

Martin: sure, I would be happy to help how I can, though my time is somewhat limited. I'm in the US on the east coast btw.

To both: I did some quick looking around and found there was an npm package that interfaces with the api! It's called google-vision-api-client. It doesn't work out-of-box, but works with 1 quick modification - the API url it's pointing to. I threw the code up on GitHub: https://github.com/jugaltheshah/visionapitest. The modification is detailed in my test.js file.

Correction: I reached out to the developer and he kindly updated the URL - google-vision-api-client now works out of the box! Will update test.js when I can to reflect this.
