Hello, there.

I would like to know if there is any way to use Azure Computer Vision but without depending on internet connection. I am developing a Xamarin Cross Platform App that makes use of OCR Functionality. This App will not have Internet connection everytime so, I require to do a solution that can perform OCR without internet connection.
So far, I have not found any solution or documentation about this.

Any help would be appreciated.

Regards.

Jovan.

    Take a look at Xamarin.Tesseract , it is a wrapper for Tesseract OCR library. For Android tess-two is used and for iOS implementation from gali8 (v.4.0.0) is used.

    usage

    //Android
TesseractApi api = new TesseractApi (context, AssetsDeployment.OncePerVersion);
//iOS
TesseractApi api = new TesseractApi ();
await api.Init ("eng");
await api.SetImage("image_path");
string text = api.Text;
