Namaste Aniruddha,

I would like to create simple android app where I would like to detect document and it boundary and auto crop image.

I saw you are doing it in your app, as below (automatically detect the edge of the paper over a contrasting surface).

Please let me know, how to achieve it and is there a guide or pointer to follow so that I can create the simple app.
