Improve Accuracy of Android TessBaseAPI (Tesseract) OCR
===

I am using TessBaseAPI for OCR in my project with the help of following LINK.
http://gaut.am/making-an-ocr-android-app-using-tesseract/
But their result is 50% to 60% by using 5MP Camera. I want to improve accuracy of my OCR.

VietOCR also use tesseract for OCR but their result is amazing and above 90% accurate. But accuracy of my application is not good.

Please help me out from this problem.
