Easy-Ocr-Scanner-Android

Easiest and simplest OCR scanner library for Android built using Tesseract and Leptonica.

About

Easy OCR Library is made by having only one goal in mind: Making OCR as easy as possible. (Don't you just love when things actually mean what they show).

Easy OCR uses a fork of tesseract, Tess Two. But deals with all the pain of setting up and building the library using NDK.

Usage

Using EasyOcrLibrary is as simple as it can get.

Step 0

Copy your trained data file into the assets/tessdata folder. You can download the required .traineddata file from here.

Step 1

NOTE : "eng" is the name of the traineddata file as here we are using eng.traineddata .

 // initialize EasyOcrScanner instance.
mEasyOcrScanner = new EasyOcrScanner(MainActivity.this, "EasyOcrScanner",
        Config.REQUEST_CODE_CAPTURE_IMAGE, "eng");

Step 2

Implement java EasyOcrScannerListener.

implements EasyOcrScannerListener

Then define the callbacks.

Step 3

Start the scan!

mEasyOcrScanner.takePicture();

Step 4

Call java onImageTaken() in java onActivityResult()

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        // Call onImageTaken() in onActivityResult.
        if (resultCode == RESULT_OK && requestCode == Config.REQUEST_CODE_CAPTURE_IMAGE){
            mEasyOcrScanner.onImageTaken();
        }
    }

And you are done!

Get the scaned text in the callback java onOcrScanFinished().
