I am trying to use the tess-two library to recognize text from imagae. Here is my code: load.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // recognize text Bitmap temp = loadJustTakenImage(); //loads taken image from sdcard Bitmap rotatedImage = rotateIfNeeded(temp); // rotate method i found in some tutorial String text1 = recognizeText(rotatedImage); } }); Recognize text method: (tessdata folder is in Download with the eng.traineddata and other files) private String recognizeText(Bitmap bitmap) { // TODO Auto-generated method stub TessBaseAPI baseApi

I've found an online guide which says I have to create a folder in the assets folder called "tessdata" and put the eng.traineddata and the osd.traineddata in this folder. I've tried but the download process still starts when I install the app for the first time. What can I do to make this app completely offline? First, in your project directory in computer (

I'm currently writing an Android application which needs to use OCR within it. To achieve this I am using Tesseract in conjunction with the tesseract-android-tools project . I have managed to get the Tesseract API to initialize and need to use the following setImage function: void com.googlecode.tesseract.android.TessBaseAPI.setImage(byte[] imagedata, int width, int height, int bpp, int bpl) What I am struggling with is how to get the correct values for bpp (bytes per pixel) and bpl (bytes per line). Does anyone know how I can get these values? I have put fairly random values in there at the
