I have tried 3 methods.
1. Tesseract IMG output --psm 0 command on terminal which gives orientation 
info but it's not always correct
2. In 2nd method I tried Hough lines Opencv algorithm which is also used to 
detect orientation detection but it's not always giving correct results.
3. In 3rd I tried Opencv Bounding box algorithm

So, I wanted to know if there is some method that exists and some of you might 
know of which given accurate results for orientation detection

Thanks again.
