## Overview

This is a sample project demonstrating how OCR (optical character recognition) can be implemented using Google Vision library.  

Apk file is available [here](https://github.com/alexzaitsev/ocr-google-vision/releases).

*Benefits:*

* requires no internet connection

* very fast

* out-of-the-box solution

* super-easy to implement and requires less than 1h

*Drawbacks:*

* understands English and digits only

As you may see it recognizes written text easily.

## Which digits it can recognize

So it recognizes without any problem the next numbers:

![recognizable-01](https://github.com/alexzaitsev/ocr-google-vision/blob/master/additional/recognizable/01.png "recognizable-01")

![recognizable-02](https://github.com/alexzaitsev/ocr-google-vision/blob/master/additional/recognizable/02.png "recognizable-02")

![recognizable-03](https://github.com/alexzaitsev/ocr-google-vision/blob/master/additional/recognizable/03.png "recognizable-03")

And the next ones it cannot recognize:

![non-recognizable-01](https://github.com/alexzaitsev/ocr-google-vision/blob/master/additional/non-recognizable/01.jpg "non-recognizable-01")

![non-recognizable-02](https://github.com/alexzaitsev/ocr-google-vision/blob/master/additional/non-recognizable/02.jpg "non-recognizable-02")

![non-recognizable-03](https://github.com/alexzaitsev/ocr-google-vision/blob/master/additional/non-recognizable/03.png "non-recognizable-03")
