I am getting same issue
@nishantsingh1814 are you able to solve it?

I found that the issue is in List<Mat> getProcessedImage method.

preProcessorRecognition = commandFactory.executeCommand(resources.getString(R.string.crop), preProcessorRecognition);

Cropping creates submat which is not continuous and has a different size. I removed this code because the images already cropped at the moment of this code.

I seems that the project has been dormant because nobody responds to the question and the pull request.
