I am a student working on a school project to create a business card scanner to extract the text from image and display it accordingly by name, phone number, etc into respective text boxes.
I have been googling for the past few weeks and found many great examples online. Currently I am trying to implement the source code from this application I found online called "AndrOCR". However, I have encountered some error in the codes in which I do not know how to solve in Ecilpse(juno).
I have already implemented tess-two from rmtheis and able to run some other OCR source codes. However, for "AndrOCR" I am unable to solve.
The codes with the error are shown below:
public void onDialogSingleChoice(int dialog_id, int item){
switch(dialog_id){
case SEGMODE_DIALOG:
mSegModeID = item;
// Change the OCR page segmentation mode
switch (mSegModeID){
case 0:
mSegMode = TessBaseAPI.**PSM_AUTO**;
break;
case 1:
mSegMode = TessBaseAPI.**PSM_SINGLE_BLOCK**;
break;
case 2:
mSegMode = TessBaseAPI.**PSM_SINGLE_LINE**;
break;
case 3:
mSegMode = TessBaseAPI.**PSM_SINGLE_WORD**;
break;
case 4:
mSegMode = TessBaseAPI.**PSM_SINGLE_CHAR**;
break;
case 5:
mSegMode = TessBaseAPI.**PSM_SINGLE_BLOCK_VERT_TEXT**;
break;
}
// It's not needed to restart the whole library here
removeDialogFragment("segmode_dialog");
Toast.makeText(mThis, getString(R.string.selected_text_layout) + " " + mSegModeArray[mSegModeID], Toast.LENGTH_SHORT).show();
break;
case LANGUAGE_DIALOG:
mLangID = item;
// Change the OCR language recognition
mLang = mTessLangArray[mLangID];
removeDialogFragment("language_dialog");
setTessData();
break;
}
}
The error occurs in the bolded text as shown above. The error message is "PSM_AUTO cannot be resolved or is not a field" for the first error, which also apply to the rest.
The source code is available in this link: https://github.com/TheWall89/AndrOCR
Please do check it out and let me know what the error are and how I can resolve them, as I am still a beginner at android development and require much help, thanks a lot~
Those constants were moved to an inner class called PageSegMode.
So change your code to
mSegMode = TessBaseAPI.PageSegMode.PSM_AUTO;
and
mSegMode = TessBaseAPI.PageSegMode.PSM_SINGLE_BLOCK;
etc.
