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