Is there algorithm or process to Isolate the text from the background to make better performance?

app crash while "onOcrScanFinished(Bitmap bitmap, String recognizedText)".
any solution to this??

please add a dependency so it will be easier to import the library and also I tried adding the directory (after downloading) but it is still not working.

here is error code

Hi,

Building the sample app, I get the following crash when returning the image to the activity:

This is the worst example on how to use a library. No examples provided

java.lang.SecurityException: Permission Denial: starting Intent { act=android.media.action.IMAGE_CAPTURE flg=0x3 cmp=android/com.android.internal.app.ResolverActivity clip={text/uri-list U:file:///storage/emulated/0/EasyOcrScanner/1525235581304.jpg} (has extras) } from ProcessRecord{ab4ef9d 24823:com.example.umangthakkar.electrofycustomer/u0a200} (pid=24823, uid=10200) with revoked permission android.permission.CAMERA

Please give the solution

possible to gather all text results at once from all containers?

I would like to get some help if possible . I'm trying to detect business card using my Android phone camera but I don't know where to start. so i can Extracting text from image using OCR and process it to read business card..
