We have a requirement , where users scan documents and it comes with some

Because the definition of "blank" can vary.
Is a page that contains an all white image blank? What
about one where the content is outside the visible region? Or one
with no standard contents, but with fields and annotations?
You need to first define what "blank" means in all aspects
of what can be rendered onto a page by PDF....THEN you can start to
determine how to programmatically find these things.
So yes, it IS difficult....must it's also VERY well defined...
